It's always too early to quit.

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

If you've got a talent, protect it.

Know or listen to those who know.

To know oneself, one should assert oneself.

If you think you can do it, you can.

Who seeks shall find.

By failing to prepare, you are preparing to fail.

Do not weep do not wax indignant. Understand.
