It's always too early to quit.
Go for it now. The future is promised to no one.
After a storm comes a calm.
To know oneself, one should assert oneself.
If you think you can do it, you can.
Never complain and never explain.
Things do not happen. Things are made to happen.
Always desire to learn something useful.
Know or listen to those who know.
The wise does at once what the fool does at last.
Men would live exceedingly quiet if these two words, mine and thine, were taken away.
