I am active members of Adsense forums. Which share adsense revenue with its members called adsense revenue sharing program. Most of the time these forums threads is filled with people who really want adsense account from Google. Well Google is boss and dominate in search engine market. Have offices in most places of world. I saw many peoples and from abroad failed to create adsense account. If they failed once their is very less hope getting their adsense approval.After several attempts many of them fail. Rarely, i saw people who got adsense approaval after rejecting.
I my view you should start one separate blog. If you make blog on separate domain it is good. Yes, i am running on blogger but and suggesting you to open separate domain blog, because separte domain shows that you are long term and serious in blogging. And after adding good content your chances of adsense account approval will be more.

How to get adsense account approval
1) Method one: Buy one domain. Host it on Paid hosting services, free blogger or free hosting services. If you use blogger then you can't use wordpress. And if you use free hosing services then you can definitely use wordpress. I suggest you to go with freehostia and 000webhost. If you don't have idea how to use wordpress then use blogger for your domain.
2) Method two: Use co(dot)cc free domain from them and host it in your blogger or free hosting as mentioned above. This is completely free domain and you can either host it on blogger or free hostings. If you go with free hosting then go with free hosting services which have fantastico or elephantia one click installer. With in few minutes your wordpress blog will be ready.
3) Method three: Use blogger for blogging and then apply for adsense. But these days getting apporval from blogger blog is difficult. But this another good option if you really add good content. Also, you earn money from other adverts like Adbrite etc..So, this is not bad idea. You can earn money from your blog if your adsense approval failed. I hope not.
4) Method four: Adsense revenue sharing websites. Their many adsense revenue sharing website and blogs. Which share its revenue with its members. This is good option for getting adsense account approval. But some times if you failed to get adsense approval then. your all content revenue will be earned by website owners. That's why, this is my method four.
These are few options options for getting adsense account approval. Buying separate domain is best option, i beleive. And professional too. This shows you are serious and valuable publisher of future.
