How often do you upvote? For most users they are under-utilising their upvote. Your vote power regenerates 20% per day (you can check the current vote power at https://steemnow.com by entering your username in the top right) and each full vote uses 2%. This means that you can give a full vote 10 times per day and be back at full power by the following day. If you have more than 500 Steem Power you can adjust the power of your vote to spread your votes across more posts. I have noticed that many accounts (my own included) aren't making full use of their votes. There is lots of great content on Steemit and you (and I) should be rewarding it. (Nb: there are a small number of overly generous people who have burned their vote power really low - if your vote power is below 20% you are probably over-doing it and this message isn't for you - but kudos for being so generous 👍)
