No matter the subject, I will never think suicide is a vaild option. People often take their lives for granted. Although we are only a brief blink of an eye in the grand scheme of the universe, Your life is HUGE to the people you surround yourself with. Friends, Family, Co-Workers.
You think you're average, Then just don't settle for average. Find something you enjoy and really get into it. It can literally be anything. Get a gym membership. It kills lots of time, You will feel better about yourself as a person and although it won't make a difference for the first couple of weeks, When you start seeing an improvement your self confidence will be so much greater.
Have faith in yourself, Man. I have no idea who you are, But live in the moment and live for yourself.
Take a week away someplace that you would never think of going, And go alone.
Meet new friends, Learn new things. You're not insignificant, You just need a reason to live for yourself.
