I have to be happy to survive

I remember the time when I was in 7th standard. When things were much simple and the only time I got worried was when the teacher walked into the class with a bunch of checked exam answer sheets. That's it, that was the only thing for which I would get worried at that time. For everything else I used to be so chilled and so casual. I miss those days. The days passed by and everything changed, no more school, college days made me realize some bitter truths of life. Now I am no more the same person I used to be, I am more worried about things that don't even matter. Less chilled. Taking everything seriously to a point where it starts getting out of control and  becomes painful. But I have only been here for 19 years, I'm still learning to live and starting to crawl. Maybe someday I'll get over all of this and find the ultimate truth. Maybe someday I won't be having anything to worry about. But until that day, for now, I will try to be happy, as happy as possible. Be positive by avoiding all the negative thoughts that try to get into my mind because the truth be told, all of this would ultimately come to an end and none of the worries and problems would matter.
