It's always too early to quit.
Go for it now. The future is promised to no one.
After a storm comes a calm.
Do not weep do not wax indignant. Understand.
Be thine own palace, or the world's thy jail.
If you can dream it, you can do it.
The most effective way to do it, is to do it.
Expect problems and eat them for breakfast.
If you think you can do it, you can.
Without hard work, nothing grows but weeds.
To have some idea what it's like, stand in the outside lane of a motorway, get your mate to drive his car at you at 95 mph and wait until he's 12 yards away, before you decide which way to jump.
