It would seem in my life-long experiences the “why” is more important than the “how.” Why you choose to commit to something in the long run has more staying power than focusing on “how” your going to accomplish it.
Because there are numerous – if not hundreds – of ways to manifest something you have clarified into your life as a goal and there may only be a couple – if not one – reason you will stick with it until you make that happen. That’s the difference. You will figure out the “how” as long as your “why” is a strong enough bond to keep you engaged.
The “why” has changed for me over the years as I mature in age. What I thought was a “why” didn’t last for me. Therefore, I had to re-examine the “why” as well as the goal itself. And yes, both have evolved and changed over time. Just as I have.
