Aesthetics are what comes last when I think about bodybuilding.
.... there's something awkward about that part. This is my suggetion;For me, bodybuilding has very little to do with aesthetics.
For me, bodybuilding requires a set amount of discipline and commitment which shapes how I am as a person in other aspects of life.It requires a discipline, commitment and hardworking that shapes me into the person who I am in every aspect of life.
While almost unrelated, bodybuilding reinforced my decision to become a software engineer. To see significant results in my body, I had to devise personalized workout programs and diets through constant trial and error. The enjoyment that comes off of creating something successful after tedious work is unmatched. As a software engineer, knowing that I will be creating programs which significantly effect someone's life is wonderful.
Interesting, but I think you better bring in some sort of correlation between bodybuilding and software engineering at the begining of this section.
