All or nothing thinking.
This can lead to great focus on a goal. It causes bursts of motivation followed by intense action and often some cool results - but it comes with a cost.
Once that initial motivation is spent, or the plan doesn't quite go to plan, the results don't quite measure up or we are unable to take action 100% exactly as we'd like, we then reach an important crossroads.
I call it the, "F*ck it" Junction.
It's here we "fall off the wagon" and revert back to type.
Undoing all your hard efforts and dragging you further from your desired goal. But there is another way.
Rather than "all or nothing" look at it and act along a continuum - from worst to better to best.
Understand that at any one time you are along this continuum and your actions will reflect this.
Essentially you don't "Fall off the Wagon" and have to get back on it - starting from scratch.
You simply stay on the wagon, and "change speeds" as you travel along the continuum as your situation, lifestyle and behaviours allow.
If you are constantly falling off the wagon, it means you were never in balance to begin with.
