I can, therefore I am.
Go for it now. The future is promised to no one.
If you think you can do it, you can.
If you can dream it, you can do it.
Things do not happen. Things are made to happen.
The dog that trots about finds a bone.
Only the educated are free.
Expect problems and eat them for breakfast.
The most effective way to do it, is to do it.
Begin to be now what you will be hereafter.
I've been a teacher at the college level, in composition mostly, and I've been an editor on magazines.
