Why do we feel the need to self improve, is it for extrinsic or intrinsic value ??

Do you as a person look to improve performance within a skill-set for the internal ‘buzz’ feeling of self-worth or is it more to do with external factors and the need to impress.  I think it says a lot about you as a person and what motivates you to succeed.  It will also determine the sort of path you take in life and how you approach.

For me I am very much driven by extrinsic values, I want to succeed not just for me, but i want to achieve (normally as part of a team) for others as well.  By improving my performance and upping my game then I get both of these.

So what motivates you ??
