"First of all, I love your take-action attitude. That's probably the most important key to success." Thanks! "Instead of working on these random niche adsense sites, why don't you work on building a site around a topic you're actually interested in? Build great quality content, build an email list, build applications that help your target audience." That idea came on my mind while I was making my 'random niche adsense site'.But I thought that I don't have enough experience,knowledge,etc to build something like that.So i decided to start making small niche adsense sites. But that is definitely something I will work on in near future (in my spare time) Thanks for advice!
