I’ve borrowed this maxim from Seth Godin (https://seths.blog/.)
The tricky bit about this is that the “hard part” is really good at misdirection. Have you ever needed to work on a big project for work, but instead you clean out your garage? It’s easy to make the argument that cleaning out the garage is hard work, but is it the hard work?
The hard part is the part you’re avoiding.
The hard part is the part that’s uncomfortable.
The hard part makes you feel vulnerable.
The hard part is the place where you may fail.
If you tackle it first, the rest is easy.
