You can not cross the gap without taking a leap of faith.
You can not keep going unless you take one step at a time.
[Following feedback from one of my best critics, I've added a concrete example at the end.]
The other day, we had a discussion about making change.
The topic was a how to make a change (lose wait, take up jogging, learn a language) - and make it stay.
The two sides of the discussion were basically "take one small step at a time" or "take a leap of faith".
After lots of give-and-take which I'll spare you, I believe the answer is:
Take a Leap-of-Faith, One Step at a Time
I'll explain:
If you only take a leap-of-faith, you risk "biting off more than you can chew", and give up too soon.
If you only take one-step-at-a-time, you risk progressing too-little-too-slow, not feel or see any difference, and as a result, give up too soon.
So do both.
Your initial resolution must be made of both parts:
Take a leap of faith, making a larger-than-you-thought-you-can-do commitment, which will get you started down a path when you'll see an immediate difference.
Take one step at a time, making a commitment on a regular-schedule, made of many small steps, that will "nail" in the commitment and keep the change going and growing.
Take a Leap-of-Faith, One Step at a Time
Good Luck!
So if, for example, your change is to start - and continue - running, then:
Decide you're starting to run:
Tomorrow (or even now)
How many times a week (at least 3 - anything less is too easy to lose the change)
And what distance - or how long (less critical - it's a small step - and you can consider increasing the distance - or duration - later.
