>>20151463Everyone has a baseline for all their traits, but their environment and conscious effort to change overrides it, possibly even establishing new baselines. It's rare for people to change dramatically though, since it takes tremendous effort.
People obviously have aptitudes for different skills and traits. If you take a graphic designer, and try to make them a programmer, if that person from a young age had a proclivity for visual design, he would be happier to stick with graphic design rather than trying to learn programming.
I feel as though behavior feels natural if it resonates with your historic behavior. The graphic designer example, is he happy doing graphic design because it's his innate life calling from birth? Or was it because he had good experiences as a kid doing similar things? It's probably a mix, but I'm convinced that if you wanted to radically change your life, it's a matter of getting a history of behavior established, so that future behavior can resonate with it and feel natural.
Optimism can be learned. Be among optimistic people will help, being optimistic and following through with plans or ideas will help. There are also fundemental reasons to be optimistic, it's not like cynicism is truth.
Personality is a habit, we all have our default behavior, but it is still a habit.
