OK Vikas, chill!
You have a good beginning in online sales/marketing whether you know it or not, -- with FB, Twitter, YT, etc. You have laid a good foundation to launch a multipronged money-making strategy. So that's a huge huge plus for you.
Having said that, now you need to concentrate on those bases and do some serious reading on how to create money opportunities out of those projects. I'd advice you to make up your priorities among those and start working.
There are plenty of materials on each of those topics -- basic to advance levels, step-by-step methods, pdf's, tools, and sw's, etc. -- on our forums. Elsewhere, you may use G and search for the pdf's initially -- if you know how to do it, you can literally get all-round knowledge and inside information of how to strike gold. Most of those pdf's are cr@p material, but you can even turn some of those into gold if you apply your own brain power to it. In between those cr@ps, you'll find real hot working nuggets, and hence you need to sift that cr@p...
Don't worry about how to use the knowledge -- just read and absorb the basics of making money on those sites/topics individually. Once you know how it works for others, you'll automatically begin getting ideas!
Do it fast and get over the laziness, else all those downloaded materials -- as well as your luck -- will gather dust.
HTH!
