I think it depends on what value is expected from obtaining the physics knowledge...that is solving engineering problems is different from astronomy is different from becoming a more well rounded individual. The best approach to each entails different levels of formality as does the best approach to each for each individual.

What about physics interests you?

I'm curious about how the universe works and want to understand why things are the way they are.

That's quite vague. Best to start at the bottom and work your way up. As in take the undergrad route until something tickles your fancy.
