Make sure you make the best out of your life; it is indeed too short to even waste it on unnecessary things that are most likely unworthy of our time. In the end, we'll all have this question, "Did I live my dream?', and at that moment, we surely don't want to regret it. Perhaps, you'll never know when you'll meet death or when will the world end, so make sure you've achieved whatever you wanted before its too late. Walk towards your dream, and everything else is secondary.
