ok, lately ive ben thinking about setting up a website and add adsense on it. i know i have to have a niche, but its like all the things that i love are very competitive. i love, anything that has to do with the brain, like mental diseases anpsychologygy, i love talking about finding money for college (grants and scholarships). all these according to google keywords traffic are very competitive niches. what should i do. should i go for the competitive once that i love or choose somethingng i would like to know more about instead?
