The downsides to always adapting, always flexible, always changing gears could lead to a lack of direction and commitment. In turn, a lack of direction could lead to failure.

We don’t want to entertain the possibility that it might fail. We just imagine that things are definitely going to work.

It is probably better to say "this might work" when you start because you’ll be much more alert to take in signals, new information, tweak it, adjust it, adapt, or maybe just stop.

Think about your actions as experiments that generate information rather than definitive decisions. It will make it easier to move forward, adapt, and adjust.

If you’re always keeping your options open, you’re constantly second-guessing yourself and that makes you unhappy.

The moment we commit to something, we start being happier with whatever we decided on. This downside is only relevant when there is no new information coming in. Adapting in uncertain situations, when we're still learning new things, makes us better.

There needs to be a balance between adapting and committing.
