Beginners thoughts

It nearly took me few years to actually come to this decision to finally starts writing but I'm still confused that what should I write? a few days back while traveling to some place, one good friend of mine actually persuaded me to really ponder upon this Idea and result of that persuasion is in front of you.Now another Problem was 'What to write?'.and this was a series problem.I mean yeah It looks cool when you say or decide ''well I'm gonna write'' but when you pick up your pen and starts to think you actually get to know how good you are.Then someone told me that write on ''what should I write''.And here you are reading on ''what should I write ''.To conclude my document I must say, you all should write even if you don't know hit upon anything at least you can write better than what I write.
