well, you don't need to afraid if you want to invest on some good thing like own blog / site.
1 domain and 1 hosting will only cost you $15 per year in minimum.
But I believe, we c an get more than $15 per year from that investment.

If we're not moving on, then we will lose the opportunity and keep earning like this for ever.
Ok, then I will look into it. I will first start-off with one domain. I noticed that your two sites in the signature is looking professional and hopefully one day I too have such kind of websites.
