I understand well that feeling you have, sometimes I feel the same way, I even ask for permission at work, I don't go and I start to wander around the city, to see people, and I have even gone to the movies alone. My mind starts to wander and I look for a solution to a problem that doesn't really exist. Sometimes we get too philosophical and the best thing to do is to go on with our lives, we don't know if our peace of mind and joy is yet to come.
Hmm this is actually deep but feels good to know I'm not the only one who have actually felt this way.
