It's always too early to quit.
You never know what motivates you.
Go for it now. The future is promised to no one.
If you think you can do it, you can.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
Either you run the day or the day runs you.
If you can dream it, you can do it.
Leap, and the net will appear.
The most effective way to do it, is to do it.
One reason the human race has such a low opinion of itself is that it gets so much of its wisdom from writers.
