Nothing is a 'loss' -- always think of it as a purchase.

For $1000 you bought out of a situation that would have cost you far worse in a very short time. It was a great buy. And you also learned a framework for budgeting that will be an advantage to you for your whole life.

Sometimes it will seem that our lessons would have been less expensive if we'd been more careful or gathered more information before we acted. Don't fall into that trap -- there also will be times when it's the other way around and it will seem like we missed opportunities because we weren't willing to act fast and take more risks. What matters is: (1) Did you make the best decisions you could with the information you had at the time, and (2) Did you make the right corrections as soon as you knew more?
