Go for it now. The future is promised to no one.

The wise does at once what the fool does at last.

Be gentle to all and stern with yourself.

It's always too early to quit.

Be kind whenever possible. It is always possible.

Wherever you are - be all there.

To know oneself, one should assert oneself.

The most effective way to do it, is to do it.

Always desire to learn something useful.
