I will start at the beginning of the day/week/month/year. Then, when they miss that 9:00am start or Monday, or the 1st of the month or year, they'll say... "Well, next beginning of the day/week/month/year."
And that, ladles and jellyspoons, is utter horseshit.
It's excuse-making.
I blame new year's resolutions, myself. It's a new day! It's a new week! It's a new month! It's a new year! Let's start it off right! Oh... we missed it. Oh well. Let's just give up until the next new whatever.
Stop right there, you. Yes. You.
You don't need it to be a Monday for you to start doing what you need to do to achieve your goals. Tuesday works too. So does Wednesday. Hell, any day works. This arbitrary threshold of "Monday" is nonsense.
There is no "one day." There is only today. Grab it and go.
The hardest part of anything is the first step. This mysterious myth of beginning something at the beginning of a totally unrelated thing must go. If you are going to achieve your dreams, you have to start now. This minute.
Take that step, and the rest will following more easily, until you are sprinting headlong.
So, stop reading this post. Take a deep breath, lift your foot and stride out.
You've got this.
