There are many ways to show that you have perseverance. Going through university/college is but one. Also IMHO college/university has to be one of the best places to meet like minded people. If your aim in life is to work at a company where you have to tick boxes and go through a hiring dept which hires you based on some grades, then sure - get the grades. Personally I've never been at an interview where they care what grades I've got, they care what I've done, and what I've built.
