It’s easy to slack, to lose an habit, because we tend to fall for our traps.
laziness is first, and it’s one of the many things we have.
I myself tend to avoid things too, and writing (lately) has been on of those things, but I know I shouldn’t.
Keeping up with what you preach and promise is part of how you define yourself and your integrity and it builds up the way you “live” the world.
If you ignore this and let the slack grow over you you’ll end up being a version of yourself you didn’t expect.
