If you think you can do a thing or think you can't do a thing, you're right.

Whether you think that you can, or that you can't, you are usually right.

It's not what other people believe you can do; it's what you believe you can do.

It's not what other people believe you can do, it's what you believe.

You can do what you think you can do and you cannot do what you think you cannot.

I do my own thing. And I believe what I do is the right thing.

If you have to do it, then you're doing the right thing.

You have to do what you believe in.

When someone says you can't do what you know you can do, then you can't do anything.
