Take an hour or two for yourself today. Take a walk or close the door and relax in private at home. The important part is to create some solitude to think a bit.
What are you hanging onto that you should let go of?
What emotion do you keep stoking the coals of out of habit, but really are ready to move on from?
Is it time to stop grieving and resume living? Time to abandon chewing the bones of that old grudge? Time to move on from longing for someone who isn't the one for you? Time to quit swallowing your pain and cutting someone far too much slack for the hurt they cause you?
Meditate on where you spend your emotional energy and what kind of life that is giving you. If it's not the life you want, start changing it.
Right now. Today. Just change your direction and step towards where you want to be.
