Struggle - but in the right way.

People who really make changes, who get stuff done, often have the conviction that although they don’t know the answer to the problem, they can and will, arrive at it through perseverance and an effort of will.

Another type of person very often doesn’t know for sure that they will find the right answer to their problem but they know with real conviction that their current trajectory is not taking them where they want to go; so they just keeping making course-corrections and trying different things.
These are the kinds of people that make lasting changes in the world.
