Words to live by.

"A good driver knows how to drive backwards"

But now, for srs.
What I often find myself saying is " Better say 'At least I tried' than 'I should have tried' ".
"Every problem has a solution. Every solution has problems" <--- One of the more meaningful things I've heard in my life. The more solutions we make, the more problems we bring up. It's like a hydra. So, in other words, KILL IT WITH FIRE!
Explanation:

"Believe what others have proven for everyone. Know what you have proven for yourself."
The last one I haven't heard anyone say, but it isn't anything I've made up myself either. Kind of hard to explain. It's not that I live by it... It lives by me... If that makes sense.

From my cello teacher:
"Practice doesn't make perfect. Practice makes permanent"
And from me:
"Trust few people none of the time, some people some of the time, few people most of the time, and one person all of the time. That person is yourself.:
Forget who wrote this one:
"If at first you don't succeed, try, try again. But then give up. There's no point in being a damn fool about it."
Anonymous, I think:
"Live, laugh, love"
And lastly, from somewhere online I read I really liked:
"I don't suffer from insanity. I enjoy every minute of it."

Neil Gaiman

Very important quote. If a society turns in on itself, regulating the private lives of each other, no one will have the political power to protect themselves.

The Gaiman quote is from the earlier Martin Niemöller reference;

    "First they came for the communists,
    and I didn't speak out because I wasn't a communist.

    Then they came for the trade unionists,
    and I didn't speak out because I wasn't a trade unionist.

    Then they came for the Jews,
    and I didn't speak out because I wasn't a Jew.

    Then they came for me
    and there was no one left to speak out for me."

"All play and no work makes Jack a mere toy."

Here's two I've come up with in reference to the internet.

When you say you're bored, what you're really saying is that you're boring.

The internet is the antisocial way of being social.
