Holding Pattern

Why is it so hard to let go of something that clearly isn't good for you?
It's that same old magic combination of holding onto the past (and waiting for it's return) or dreaming of the future. We can live in that holding pattern for a long freaking time, even though the 'now' has been pretty awful for a pretty long time.
If it's causing you pain, if it's bringing any kind of negativity to your life - flip it round as fuel, or let it go.
Now, time to listen to my own advice...!
