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

Without hard work, nothing grows but weeds.

Expect problems and eat them for breakfast.

It's always too early to quit.

Be thine own palace, or the world's thy jail.

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

By failing to prepare, you are preparing to fail.

Know or listen to those who know.

Do not weep do not wax indignant. Understand.
