Upvoting your own comments to make money is one way of doing it.

Wouldn't it be better for the platform (and ultimately the price of Steem - Your investment) if you spent those upvotes encouraging content creators to produce more quality content and working on more content yourself?

At your current SP level your upvote is worth ~$0.01 and you can do that 10x a day. You also need to create a post or a comment to be able to upvote it.

I'm not coming from a judgemental angle here, it just seems like a lot of effort to gain $0.10 a day.

I'll save you some time today & upvote you for that $0.10 so you can spend it on others.
