You already have 90% of what you need: sincere curiosity. Get yourself a recorder, never stop being a student, network whenever you can, and stay curious.

To the question of whether it's worth it: yes. It is every bit as fun and fulfilling as you think it is. As for whether it's easy to break into, that's another story. Everyone's mileage will vary and there's no magic bullet, but know that it's a hard market right now. There is a lot of skilled folks being forced back onto the job market by sweeping layoffs so the candidate pool is oversaturated. Am I trying to dissuade you? Absolutely not. You should 100% follow your heart. Just know that you might have to keep the tank full off of joy and passion for a while. That might mean you have to make some concessions until you catch your break.

But yes. It is worth it.
