Failure is enriching. It's also important to accept that you'll make mistakes - it's how you build your expertise. The trick is to learn a positive lesson from all of life's negative moments.
I know I should have never got into politics. And I've learned my lesson. No more politics.
One lesson I learned from 'The Monstrumologist' was never to get too attached to your own characters. That's harder in practice than in theory. At the end of the third book - which coincided with the end of my contract - I was an emotional wreck. I mourned Will Henry and Warthrop.
There is a lesson there about greed and it is a lesson I am willing to learn as well. Has it made me a distrustful person? I don't think so. But we probably look a bit more carefully at our financial situation now.
Anything that confirms for me the transitory nature of reality isn't bad. It's a good lesson in human hubris.
The lesson of Pearl Harbor ought never to be forgotten, and of course the motto that came from that, 69 years ago, the war which my dad fought, was 'Remember Pearl Harbor, never again.' We need to keep that to mind.
I can go into any working circumstance and, simply, I'm prepared to deal with the work. It was a long, hard lesson I learned.
We are supposed to enjoy the good stuff now, while we can, with the people we love. Life has a funny way of teaching us that lesson over and over again.
I had my Aunt Rosie, who was famous and then not, so I got a lesson in fame early on. And I understood how little it has to do with you. And also how you could use it.
Biggest lesson I learned my first year in the NFL is no one gives a crap about what you did last week. This league is about what have you done for me now. That's the NFL. It's also our culture. So you keep working hard because that's the biggest truth about football.
The biggest lesson I've learned from my children is to look in the mirror at myself, not at them. I've realized that everything I've done has had an impact on them. We have to understand that they are like little paparazzi. They take our picture when we don't want them to and then they show it to us in their behavior.
I've learned the dangerous lesson of the web: You succeed by giving up control, and that's inverse of the normal campaign.
Lesson one, introduce yourself to everyone when you walk into a room. Don't act like you're too bougie to say, 'Hello.'
It takes me a while to figure things out. I usually have to repeat a lesson or two - maybe three times!
What the School for the Arts taught me was a great work ethic. They showed me - not just taught me - that if you work hard, you can see the effects. They gave me that lesson, and I have used it at every stage of my life. And I am still using it now in my new role on 'The Walking Dead.'
The big lesson of Reagan is: To think that he was some sort of simple figurehead and didn't do the thinking and simply read a script in front of him woefully underestimates him. Ronald Reagan was an extremely intelligent person with a real V8 engine under his hood.
I've always tried to control everything and every aspect of my life, and this is maybe the biggest lesson I've learnt with motherhood - you just can't control everything, and I'm much more relaxed now about unexpected changes and things that happen.
He has missed the finest lesson of culture and experience who has not learned how to enjoy without owning.
Of my old tendency to overdo the dedication and deface the title page with florid compliments and obscure quotes which the recipient cannot read, I will say only that I learnt my lesson when I had to shell out with my own money for a hardback I'd vandalised and now limit myself to 'Good wishes.'
Oh, I'll tell you about 'Anyone Can Whistle' - the lesson I learned with doing that record is that the simplest songs are the hardest to do.
Because we had no money when I was growing up, when I started dancing, I wasn't allowed to be frivolous - my mum made me go to every lesson because she was paying for it.
The one thing that I keep learning over and over again is that I don't know nothing. I mean, that's my life lesson.
I think the most important lesson isn't necessarily to try and write a different book every time, or to try and brand yourself and write one specific kind of book, but to write the kind of books you love to read.
The biggest lesson from Africa was that life's joys come mostly from relationships and friendships, not from material things. I saw time and again how much fun Africans had with their families and friends and on the sports fields; they laughed all the time.
Where there are no spectators, there is no sponsorship. Where there is no sponsorship, there is no money. Where there is no money, there are no officials with fingers in the pot. The lesson to be learnt from this is simple. If we want honest sport, we have to stop watching it.
No matter how much you've done before, you wonder if there will be a light at the end of this particular tunnel. It's the nature of the beast, and it's a part of what compels us. Every movie is a new lesson you learn making your way through it.
The historic lesson is that it was a strategic failure to go into Iraq. History will not be and should not be kind with that decision.
I love when I teach my son a good lesson. But I love it even more when he teaches me.
I learned a lesson which I didn't heed: Don't put yourself in your movies. It's too much.
I'm very happy with my life. I am what I am. I don't worry about anything that I can't control. That's a really good lesson in life.
I think an important lesson from the game is that once you have made a move, you cannot take it back. You really have to measure your decisions. You think a lot. You evaluate your choices very carefully. There's never any guarantee about what's going to follow once you have made a decision.
When I am wrong, I will learn the lesson and move on to face other challenges. For me, that's what creating your own life is. Doing your best work while being your best self.
'Buncha Losers' comedy is one of those homegrown American art forms, up there with infomercials and Elvis-shaped soap carvings. No other civilization could have invented it. The French took a stab with Sartre's 'No Exit,' but then they had to ruin it with a lesson at the end.
Military leaders, many of whom were students of counterinsurgency, recognized the dangers of an incremental escalation and the historical lesson that 'trailing' an insurgency typically condemned counterinsurgents to failure.
The great lesson I get from 'Moby-Dick' is that when the times are bad, when there is great foreboding, there are still ways to go about living. It's through Ishmael that I find a kind of overall cosmic approach to a meaningful life in this meaningless world.
The only things that are really permanent are love, family, friendship, and that is a lesson. At the end of the day, that's really what it boils down to. The rest of it is just stuff.
