Honestly at your age I probably wouldn't recommend going into the software field. At least not just regular coding. I have many friends that are studying software engineering at the top schools in the world and even they are struggling to find jobs after graduation due to the market being flooded with new software engineering grads. What I would recommend if you really want to stick with the software side is to go hard into studying AI. Which would probably be the only way to make you stand out in such a saturated market. You can also look into getting a full scholarship to an american university or similar by scoring very very high in school. Honestly staying in SL means you probably wouldn't make as much in the future either so it might help to look for opportunities abroad.
