Steemit is quite complicated as a platform. The resource limitation is necessary to prevent bringing transactions on the blockchain to a stand still. The concept of Steem Power is probably the only reason Steemit still exists at all. Without SP holders Steem coin would have even less value than it has currently. SP is an attempt to slow the downward momentum of Steem when content providers sell their earned coins in order to realize creator profits.

The important question to ask yourself is:

Why am I here on Steemit?

If you are here to post a few thoughts every now and then, resource drain shouldn't be much of an issue. I find it's difficult to write more than a few posts a day, since I have many other responsibilities in life. Steemit is currently a learning experience for me, and it's been a lot of fun so far. The important thing for a regular user (not power/purpose driven) is to stay engaged in the platform... but not too engaged.

If you are here to promote your content created on other websites, you will need to invest some time reading about how such activities are performed. There are several decent threads to check out if this is your goal. Copy/Paste plagiarism is a big problem. Thus the cheetah bot. There are some methods to verifying external content is yours, but downvoting the cheetah bot is not one of them. As far as fast growing influence is concerned, there are various vote buying services... but there seems to be a political knife fight going on with this process, so beware...

If you are here to learn how blockchain and crypto currencies function, I would recommend posting one or two random thoughts per day... and check out the Steem Engine... read a bit about the Steem API ... run Brave Browser ... sign up for accounts at least two crypto exchanges: Uphold and Poloniex .. Pass their KYC ... and have a little fun playing with the few dollars you get from random Steemit posts and watching anonymous Brave ads.
