I believe every man has a moment like this at least once in his life. It happened to me a few days ago.
You have to sit down and reconsider where you wanna go. You realize that nobody is responsible for your life other than yourself. I always thought it only happens after a drastic change, somebody you are close to dies or something. But it just happened randomly to me. I was befallen to realization. Now I know that the drastic change comes after.
