Its true, we all are, everyone in the world. Give me one person that isnt Frusterated with life, try, everyone is constantly striving to become greater, to get more women, money, fame, whatever their ambitions are. Think about it, the biggest football star at your school probably wishes he was at a different school, with more partying, near the beach or something. We are all frusterated. When you get a steady girlfriend, you will want a hotter one, if you get a hot girlfriend, you will want a wild one. So you know what you do? Stop prolonging your happiness, be happy now. That is what TAKING THINGS FOR GRANTED is, not appreciating your current situation.
