Wondering what the best place to save money, or maybe keep it in to invest.

I’m an aboriginal college student. Recently I have had more money than I know what to do with because of all the grants and everything a First Nation gets while going to school. I have found myself buying too much useless stuff and want to stop that and invest in something or keep it in some sort of savings account that gains money in the long run. I’m in business administration so I understand some aspects of investing, etc. But was looking for some direction on where to put my money. Thanks in advance! I’m a newbie to this stuff 🙂
