Go for it now. The future is promised to no one.
Begin to be now what you will be hereafter.
Well done is better than well said.
To be a good loser is to learn how to win.
Problems are not stop signs, they are guidelines.
If you're going through hell, keep going.
Who seeks shall find.
The dog that trots about finds a bone.
To know oneself, one should assert oneself.
You never know what motivates you.
I think it was T.S. Eliot who talked about good poetry being felt before it's understood. I believe that. There are some bands where I love their lyrics but I don't have a clue what they're on about.
