The problem is when we become so overloaded with the things we are hanging on to that we can barely trudge forward putting one step in front of the other.
Hanging on to jobs that you hate, grievances that have long since been settled (not always to your liking), things that drain the life out of you but have become your cause celebre and the manifest you show to the world.
The parking meter is empty. You have a couple choices here; plug more money into the meter and keep working on your grievances, your job, your cause, or recognize that this is done and it's time to move on. Change involves choice. It's yours to make.
