If you are heading somewhere, it only makes sense to team up or hang out with people headed in the same direction.
If you are interested in taking the leap, starting a new business or doing some really exciting stuff with your time, then you ought to seek out and be-friend people headed that same way.
People like you, people headed somewhere cannot afford to keep friends for friend keeping sake. Allow the people you move with to inspire you and challenge you in a healthy way, steer away from friends who have sunk into the mediocrity prevalent in the society, steer away from people who are empty vessels headed precisely no-where.
(Unless you have a S inscribed on your chest, do not fool yourself into thinking you can change them either. You are not Superman, are you?)
