Maybe not the most popular opinion here, or maybe it will be, but advice from a father of two boys: Enjoy your childhood for the remaining 3-5 years before worrying so much about your professional career. You have decades of working in software ahead of you, if you continue on that path. Just enjoy your childhood, go out and play, or even just work on projects you enjoy. Once your childhood is gone, you'll regret not…
Besides, age 13-14 is when you start high school, and that's when things get real anyway. If you intend to apply to a top school you need any advantage you can get, and work experience in jobs that are actual careers is impressive.
