We sometimes stay invested in things that we shouldn’t simply because of sunken costs. We decided to stay in something we no upside when you stay but we do simply because of the time invested in it.
We force our ourselves to finish a bad book when we don’t have to, keep pushing and paddling at a start-up because of money invested and relationships that don’t make us happy anymore.
The more time you spend on a bad book, the more time you steal away from yourself to read a good one.
Learn to free yourself from the trap of sunken costs and focus on the huge upside of starting afresh.
