Purpose of Life

When I first started working, my goal was to find a greener pasture and succeed in life i.e. getting married, having a family and living comfortably. I chose the legal field thinking that it would help me to achive all these. 8 years has since passed. Somehow, I lost myself along the way. Although I have achieved some of the goals I set for myself, I don't have the stamina and spirit to pursue further. I cannot figure out the reason for me to lose the stamina and spirit that I first had when I started pursuing my goals. The only thing I can say for sure is that I don't feel appreciated. Hence, the apprehensible solution would be to look for another field of work which can bring back my stamina and spirit. I don't think I have the guts to leave the way of life I'm leading now. I supposed the reason for taking such defeating stand is largely due to my commitments and the worry that my skills and knowledge are not good enough to compete with others. How many people can actually do what they like in their entire life? or How many people actually know what they like doing most in their life? Whatever it is, the reality remains i.e. I will continue to have this terrible feeling until I have the guts to change the way of my life right now, be it the field of work or personal. Sigh!!!
