That's why we burn the boats when we land on the beach.
Because the only way out is through.
It's pretty easy to bail out of a course (especially a free online course that no one even knows you signed up for). Easy to quit your job, fire a client or give up on a relationship.
In the moment, walking out is precisely the best short-term strategy. Sometimes this place is too hard, too unpleasant, too much…
The thing is, though, that the long-term strategy might be the opposite. The best long-term approach might be to learn something, to tough it out, to engage with the challenge. Because once you get through this, you'll be different. Better.
We always have a choice, but often, it's a good idea to act as if we don't.
