I have an Acorn investment account that rounds up my spare change transactions from my checking account and my credit cards. I also deposit a small amount monthly to it as well. In addition to what it pulls in automatically for me, I also transfer on any 'spare' money I'm able to find. I have lots of small stuff online where I collect points and turn it into cash. When I do, I put it in the investment account. Same with rewards from credit cards. I'll cash out to credit card but also deposit that amount in investment account. I've watched that slowly build, plus the growth I get in that account is so much more than regular savings account. Why am I telling you this? Well, if I ever do write for Medium and join the partner program, I plan on putting any money in that same investment account. What am I going to do with it? Not sure yet, my goal is to do something big and fun just for myself. A trip sounds perfect!
