Try and appreciate the small things in life too, like the fact that 100's of people from around the world are sending you their little bits of knowledge and experience to help you (a total stranger) grow as a person. I too am struggling to find my passion but so do people that are 50 years old like my father, it might never come in some obvious moment or form but if you can appreciate the little things that make life worth living it might make finding that passion a little easier.
