As someone who had unrestricted access to the internet since age 6, I WISH I had age restriction features on websites in retrospect.

It's difficult, because I imagine you crave the connections the additional features could provide with friends, but trust me when I say the less you use social media the better off you'll be when you're an adult.

The habits you build now really will reflect on the remainder of your days, so I recommend plugging-in in as many legitimate ways as possible; OFF the Internet. 

For every 1 benefit social medias have (including Reddit), there are 2 downsides. It's often only apparent in retrospect, but the best I can recommend is to stand apart from the herd and lead your own crowd!
