Is learning to code really worth it in the long run?

I’m 17 years old and I started learning coding (Python) about a week ago, completely from scratch, using just my phone.
I’m learning through beginner platforms like Codefobe and similar apps. In the last few days, I’ve learned:
what variables are
the difference between strings and integers
how input() works
basic type conversion using int()
simple math operations
and I built a small calculator by myself
What surprised me is that coding is actually fun. Debugging errors, understanding why something didn’t work, and then fixing it feels rewarding.
I know one week of learning doesn’t mean much, and I’m still very early. I also know learning on a phone isn’t ideal, but it’s what I have right now.
So I wanted to ask people who have more experience:
Is learning to code really worth it in the long term?
Does the motivation usually last after the beginner phase?
What should a beginner focus on early to avoid wasting time or burning out?
I’m looking for honest answers, not hype.
Thanks in advance.
