In some countries, college degrees are mandatory to obtain jobs, and you'll need one. But college is not only for learning (remember: learn by yourself whatever you want, all is accessible) college is also to meet people, to create a network in your field of interest. So use this time to achieve this, meet the futures CTOs, coworkers or maybe your future cofounders ! This is far more important than you think, and in fact, I would have liked I had this advice more younger...
