To have an idea of what the world is about I think it is important to know Physics. You often hear people discussing the nature of reality who are not familiar with Physics. And that lack seems to disqualify them. I am not saying this is a positive reason to learn physics but at least it is a side motivation that I think is worthy. Who is guilty of opinions about reality without knowledge of physics. A lot of people I know.

But what if you are not good at math.

This is the point of my comment here. To learn Physics I think one needs two things (1) To say the words and go on. (2) 10,000 hours. The last requirement is the hard one. It is the time factor that gets harder as one gets older. For this reason it is important to do this during  the twenties.
