Know or listen to those who know.
I can, therefore I am.
By failing to prepare, you are preparing to fail.
Begin to be now what you will be hereafter.
Expect problems and eat them for breakfast.
If you've got a talent, protect it.
Go for it now. The future is promised to no one.
Be kind whenever possible. It is always possible.
The dog that trots about finds a bone.
If you think you can do it, you can.
I used to joke that if acting didn't work out, poetry was my commonsense fallback.
