Humans are social animals, this is an already established fact. There may be times that we need to isolate ourselves, to turn into the Hermit so that we may learn more about ourselves and work towards our goals. However, we cannot remain separated for too long as we then fall more prone to depression, loneliness, boredom, etc. None of which allow us to live our fullest lives. Trust me, I have been there.
So, ask yourself if you've consciously, or even subconsciously, withdrawn from society. You may find that you have but you are fine. This is the quiet reflection you are in need of. Conversely, you may find that you could use a good phone call with a good friend, a coffee break to catch up, or a good ol' hanging out session and ain't no better time than the present!
Get social! Get out of your head, away from your project, and allow yourself some time to simply have fun! Not everything is supposed to be productive. You are allowed to goof off every once in a while. No agendas, no tasks to check off your list...just the sheer joy found from being surrounded by good friends. It raises your vibrations, alleviates your stress, and can even sharpen your focus and clear you head. This may be what leads to your breakthrough!
