Hello /r/asktrp, I'm an upper-middle class 14 year old teen from Australia. I found this subreddit a few weeks ago whilst searching for ways to better myself; becoming successful in society.

At the moment I have little interest in the dating scene but am looking into self-improvement in regards to working out and fitness; I am quite scrawny. My high-school offers a Wednesday and Friday gym session; I am interested in taking part in it but am afraid that this might affect my grades. Looking for a compromise, I decided to put aside 20 minutes every morning to exercise.

With this in mind, how might I improve my body without compromising on my grades? Also, what other things should I implement into my life with the goal of self-improvement?
