You want something go get it!

A clip from the movie The pursuit of happyness and some true words spoken by Will Smith.

 
Don't ever let somebody tell you...
...you can't do something.
Not even me.
All right?
- All right.
You got a dream...
...you gotta protect it.
People can't do something themselves...
...they wanna tell you you can't do it.
If you want something, go get it. Period.
