When one must, one can.
Sentiment: POSITIVE
There are things one must do for oneself.
If you think you can, you can. And if you think you can't, you're right.
The time when you need to do something is when no one else is willing to do it, when people are saying it can't be done.
He who can, does. He who cannot, teaches.
In order to succeed, we must first believe that we can.
He can who thinks he can, and he can't who thinks he can't. This is an inexorable, indisputable law.
One always has time enough, if one will apply it well.
You have to know you can first. How comes later.
If you can, you must.
Before you can do something you must first be something.
