What Career paths are best for INTPs?

I'm almost in my 30s, and I still feel lost. I tried different options in medicine, but I decided it doesn't suit me because it requires a lot of physical effort. I’m looking for something cognitively stimulating that requires creative thinking, problem-solving, or something similar.

I thought about software engineering, but I’ve heard there are a lot of layoffs and that AI is dominating the market.

I'm starting to think that I'm the problem, as I am impatient. I get bored and give up very quickly. I thought this might be an INTP thing.

I'm curious to hear about your experiences.
