It's always too early to quit.

After a storm comes a calm.

Without hard work, nothing grows but weeds.

If you're going through hell, keep going.

Do not weep do not wax indignant. Understand.

Begin to be now what you will be hereafter.

To know oneself, one should assert oneself.

Know or listen to those who know.

If you think you can do it, you can.
