Be gentle to all and stern with yourself.

It's always too early to quit.

Without hard work, nothing grows but weeds.

To know oneself, one should assert oneself.

If you're going through hell, keep going.

Know or listen to those who know.

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

Do not weep do not wax indignant. Understand.

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