How Much STEEM Power Should I Have in January 2018?

I've been on Steemit for 12 days, and to say I'm hooked is an understatement. I love the community here and the potential Steemit and STEEM has to offer, so thank you all for going along on this journey with me.

One thing I'm having a hard time figuring out is how much STEEM Power I should have in order to make a difference, even if a small one, with my vote. There are posts on this topic, but most are from a year and a half ago with users saying you need 100,000 SP (sorry, I don't have a spare $600k to spend right now).

I'm at about 29 and my votes do very little. What should I aim for right now in January of 2018?

Thanks for your help. Please vote and follow if you're interested in cryptos, Steemit, writing, business, marketing, etc.
