But I can’t think of right words to say.”

Context: Whenever you cross swords with an enemy you must not think of cutting him either strongly or weakly; just think of cutting and killing him. Be intent solely on killing the enemy. Do not try to cut strongly and, of course, do not think of cutting weakly. You should only be concerned with killing the enemy.

“If you think you can you can, if you think you can't you're right!”

“If you think you can, you can. If you think you can't, you're right.”
Variant: If you think you can, you can. And if you think you can not, you are right.

“Whether you think you can, or you think you can't — you're right.”

“You can lead a horse to Harvard but you can’t make him think.”
