The most effective way to do it, is to do it.
To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
By failing to prepare, you are preparing to fail.
If you think you can do it, you can.
I can, therefore I am.
Know or listen to those who know.
Wherever you are - be all there.
You never know what motivates you.
If you're going through hell, keep going.
I think if you're a competent actor with a good imagination, and if it's on the page, it makes your job a lot easier.
