If you've got good content, I think you would be better off with affialiate offers on your site instead of adsense. The self development world has a ton of sub-niches and all of them have a lot of affiliate programs.
Self development can be encompass many things such as learning Spanish or losing weight and you could probably do well promoting some affiliate products
I had been promoting many self development sites and observed that the Adsense ads were generally low paying. Promoting aff progs would be better.
