It is EXTREMELY difficult to only rely on your own "WILL".
Sometimes you need to, other times you tell yourself you have to because of your ego and insecurities (talking from experience)
What I've learned is consistency is EARNED. Similar to how trust is earned.
It is not a one dimensional relationship.
When you have support, accountability, and community when those weak days come (which they will), you will have those around you to inspire and REMIND you WHY you are doing this in the first place.
I'm not saying you cant do it on your own, but what for...
Do your agree?
