Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
To know oneself, one should assert oneself.
The most effective way to do it, is to do it.
If you think you can do it, you can.
Expect problems and eat them for breakfast.
I can, therefore I am.
If you can dream it, you can do it.
You never know what motivates you.
Be gentle to all and stern with yourself.
That song is a story that shows how easily you could get slipped into being labeled as the bad guy, even though what you really trying to do is tell the bad guy to leave you alone.
