Impulsively bought a domain

I liked the name and think it will for sure have a future blogging stories from people who have found yoga as a catapult into personal development, healing, overcoming addiction, improving mentally physically and emotionally. Etc.

BUT I don't know what my want my site to rank for in terms of keywords.

How do i know which keywords to start from? I have tools and know how to research. And apply but I think I just don't know what thr right choice of keywords would be used to rank a yoga blog website

Ideas.?
