Would focusing on self improvement do more to change the world for the better than attempting to change the world?

Assuming there are no answer choices, here is my answer.

If you improve yourself, you can change the world better than focusing on just changing the world, but you still need improvement. In order to change the world, you need to be fit to do so, and if you are not suitable, or don't have the suitable qualities to make a difference, then attempting to change the world would be a waste.
