It's always too early to quit.

Know or listen to those who know.

Always desire to learn something useful.

To know oneself, one should assert oneself.

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

Begin to be now what you will be hereafter.

Do not weep do not wax indignant. Understand.

The dog that trots about finds a bone.

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