If you're going through hell, keep going.
After a storm comes a calm.
Go for it now. The future is promised to no one.
To be a good loser is to learn how to win.
Only the educated are free.
Things do not happen. Things are made to happen.
You never know what motivates you.
It's always too early to quit.
Be gentle to all and stern with yourself.
Wherever you are - be all there.
I think one of the downsides of the sort of obsession with romantic love and personal fulfillment is that the plain fact of the matter is that those feelings don't last for ever and so they better be replaced and reinforced by things that do.
