It doesn’t matter what you paid for it. It doesn’t matter what you think someone else should pay for it.
All that matters is what someone is willing to pay for it.
Nothing more. Nothing less.
You have to detach yourself from whatever meaning or value you’ve assigned.
Each decision is a new one.
The past decisions have gone. The only decisions to consider are those that affect the future.
Look forward. And let go when you need to.
