It's always too early to quit.

By failing to prepare, you are preparing to fail.

Know or listen to those who know.

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

Begin to be now what you will be hereafter.

Leap, and the net will appear.

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

Expect problems and eat them for breakfast.

If you think you can do it, you can.
