I recently read Mark Manson's book titled "The Subtle Art of Not Giving A Fuck." While I didn't love the book itself, the concept is powerful. In an age fueled by social media and portraying the best version of yourself, social pressure pushes us to do certain things. Take this picture, go to this restaurant, hang out with these people. The result is an increasing lack of individuality.
Not giving a fuck, is not caring what others think and focus on what works best for you. Sure, it's easy to not care what your old co-worker thinks or a cousin. It's harder to ignore that parent who judges you or your best friend who you are distancing yourself from. Not giving a fuck, is focusing on long term results vs. short term gain.
