It's always too early to quit.
What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
If you think you can do it, you can.
You never know what motivates you.
If you can dream it, you can do it.
Know or listen to those who know.
Leap, and the net will appear.
Expect problems and eat them for breakfast.
By failing to prepare, you are preparing to fail.
I have seen doctors, in good faith, leave patients on steroids for years, thinking they are doing right. A friend of mine was on steroids for so long, she has severe osteoporosis.
