Some people spend their entire lives waiting for the time to be right to make an improvement.
James Clear, "Atomic Habits", Penguin Random House, October 2019
I am guilty of this all the time. In pretty much everything.
I don't know if I am subconsciously not willing to put in the work, or if Satan is telling me it's not worth it right now, but I always want to start improving or start a "new goal" when it fits in the calendar as a "starting point". Like, the first day of the year, or first day of the month, or a Monday, or a significant date that's memorable to me, like a birthday, etc.
Maybe it's just my procrastinative nature to "put it off until tomorrow". It's probably a combination of all the above to some degree or another. Either way...there is usually an excuse to NOT to do now.
Instead, I need to just start now, where I am, as I am. Who cares what day it is? I shouldn't!
As President Kimball use to say..."do it now"!
