It's always too early to quit.
To know oneself, one should assert oneself.
You never know what motivates you.
What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
The most effective way to do it, is to do it.
Go for it now. The future is promised to no one.
If you think you can do it, you can.
Always desire to learn something useful.
Things do not happen. Things are made to happen.
You can have a lot of unhappiness by not having money, but the reverse is no guarantee of happiness.
To me, thoughts are fun and art is fun. The strength of our society should not be idle entertainments but the joy of pursuing ideas.
