I have been reading about SEO, watching Ahref videos, and I also have been working 5 hours a week on a link-building assistant job for more than a year and a half. I want to go deeper to become an SEO writer or something similar, but I don't know which direction to take.

I was going to ask for suggestions, but I think it would be better to hear your specific stories if you don't mind. Tell me what you did well, what would you have done differently in your process of growing your SEO skills and finding your niche.
