. . . will maybe make a FB account, Twitter account, and Google + possibly? I don't use alot of social media though, so I am still unsure exactly how to get the ball rolling on this.
If you don't, then don't. Plus trying to manage multiple social media accounts spreads you out and consumes a lot of your time that would be better spent writing.
Have a newsletter and a website. Your website is your home base. Your YouTube videos plus any social media you decide to use (if you decide to use it) should all funnel people to your website. And your website should funnel people into your eMail list.
Your list and your website are the two things you control and should keep under your control. You cannot control YouTube. You cannot control Facebook. And so on. Any other sites should be used to bring people to your own website and list. Don't be dependent on Facebook fans and Twitter followers and so on. If any of those sites change algorithms or go under or start charging you an arm and a leg to reach your own followers, you're in trouble if you haven't gotten those fans and followers to visit your website and sign up for your list.
If you have their eMail address, you will always be able to contact them (unless and until they opt-out) and there's nothing Facebook, Twitter, YouTube, etc. can do about that.
It benefits Facebook and the others for you to interact with your fans on their site because it keeps traffic on their site which drives ad revenue. It benefits you to get
your fans to
your site. Facebook and the others are not your friend. They want your content, your posts, your fan interactions to benefit them. You need those things to benefit
you.
Get people to visit your website. Get them on your list.
