Thank you Demo for your responses!!
Everyone here please read this edited post. I have deleted my original content and instead am putting this comment here, as it briefly explains it all and why upvoting your own comments/spam is a bad thing. Thanks!
In my case I bought into steem with .4 BTC when it was around $1.50 or a little higher. I then used like .2 BTC worth of it to rent SP, and converted my other .2 BTC into my own Steempower.
My original math showed I would make a decent sized return of 15% to 20% if I upvoted myself(assuming I was at 100% voting power and did it at least 5 or 6 times every day). The issue I saw is that when the Steem price fell in half, I ended up going negative by 50% to 60%, with the only way of recovering most of my investment would be to upvote myself 10 to 11 times per day. I completely understand how this is a bad thing now though.
The thing I was unaware of was that there is a reward pool anw how I was draining it and giving to myself. I did know Steem miners or something was happening in the background to distribute the Steem/SBD(though I am unclear on where SBD comes from, maybe the creators of steemit).I was not versed on what a rewards pool was until I asked about why someone may be downvoting me. I feel like there is a lot more information that needs to be put out there to educate incoming Steemians. Had I understood this concept better I would not have been upvoting my own comments.
Now that I see the negative impact, because if anyone just continually upvotes themselves they can post garbage spam comments and make money while draining the reward pool. if the reward pool is drained our upvotes start to be worth a lot less. I think we would only get SBD in thay case and no Steempower reward, so your vote would be worth half...Which also eventually will turn Steemit into a spammy crappy place(I don't want that, I ran away from reddit due to that and bots/vote manipulation) because people can see others making money from spam. I feel like I have a lot better understanding now of why it is important to not upvote yourself at least on comments(but don't spam blog posts either), AND why it is important not to upvote spam people post.
Any thoughts you would be willing to add on the 
Well at any rate, thank you!!
