We abandon projects that are important. We avoid replying to the most important email.
We ignore priorities because of the resistance; that little golf ball sized amygdala near the back of our brain that tells us to flee. The difference between humans and other animals is that we can dance with the fear.
The fear of failure. The fear of taking responsibility if we're a success. If it's something we'll regret, we're compelled to act on it.
Lack of time is often our excuse to never getting started. Everyone has five minutes in their day. To have the guts to acknowledge the resistance but do the work anyway may be the bravest thing we ever do.
