Prepare for falling off the wagon
Falling off the wagon is not an issue. It’s not important. It’s certainly not a tragedy. However, failing to climb back on the wagon would be.
And so if—or when—you fall off (as most of us do), that’s the time to be helpful. Make it easy to get back on. Don’t berate yourself and feel bad. That wouldn’t serve you.
Instead, clamber back up. Take a breather. Take it easy for a while. And then, gradually, figure out where you went awry. In other words, try to pinpoint what brought about your lapse. Use your ‘failure’ as a learning experience instead. Finally, make an adjustment or two to reduce the likelihood of it happening again.
Me, I’ve fallen off and gotten back up (sometimes after a lengthy gap) more times that I can recall!
