You are focused on documenting and building the history of your life, not on living the life unfolding right in front of you. It is all about the check-in, the status update, the captured moment, rather than being fully present day to day.
Social media starts out as something you check occasionally, but before long, it takes over your life. You stop reading books or sitting with yourself quietly. Instead, you check Facebook. Then check it again. And again. And again.
Constant attention to social media comes at a cost. You lack focus because you are distracted by so many things.
When you are having experiences and documenting them at the same time on social media, you are not experiencing any of it.
But with those advantages, come disadvantages. Just as with most things in life, you need to balance the pros with the cons.
At the heart of social media are people. People that laugh, tweet, post, sing, post tweets, share good, share bad and are looking for real people to do all of the above with.
Take time to embrace the people, their minds and hearts. You can never go wrong investing in real people.
