It's always too early to quit.
Always desire to learn something useful.
Go for it now. The future is promised to no one.
Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
Who seeks shall find.
If you're going through hell, keep going.
Things do not happen. Things are made to happen.
The wise does at once what the fool does at last.
To be a good loser is to learn how to win.
I like to browse in occult bookshops if for no other reason than to refresh my commitment to science.
