If you invest a lot of time, money or effort into something (could be a project, job, relationship, customer, education or anything else), there’s a big chance that you’ll do everything to justify your investment. Even when it becomes obvious that your investment is a lousy one, you’ll try to defend it and prove that you haven’t wasted your energy on something that is bound to fail.
This happens because we can’t accept failure. No one can. And since we can’t accept failure, we keep on doing what we’ve been doing all along and we’re hoping that it will somehow turn around, that it will work out and that all our effort will be paid off.
But it won’t.
Be honest with yourself and stop as soon as it’s possible. If you figure out that your current job, project, seminar (or anything else, for that matter) is in limbo, drop it and move on. Don’t look back and don’t feel guilty about it. You did your best, but it didn’t work out. If you continue doing what doesn’t work, you’ll just sink deeper; you’ll just waste more time, more money and more energy.
There are plenty of opportunities out there to be pursued. Learn to let go (of the ones that proved to be dead ends).
