So you're not impressed with life? Feel like something's missing? Instead of wallowing in self-pity, why not try and give your life meaning? It will make you feel better and more complete.
Think about the things you care about deeply (your love life, kids, work, freedom). Identify the aspects of your life that aren't satisfactory to you and set about giving yourself targets to meet.
Knowing who you are and why you're doing what you're doing will help you give your life direction - and not just any direction. Your own direction.
