Are You Interested Or Committed?

I was clearing out my travel bag the other day and a slip of crumpled paper fell out. On it was scribbled:

There is a difference between Interested and Committed. When you are interested in doing something, you can do it only when circumstances permit. When you are committed to something, you accept no excuses, only results. 

(I researched and found that this was a quote from Ken Blanchard).

I must have heard this from one of the talks I attended in the last year. I could not even remember from where. It made me think though . . . what are the things, goals, objectives that I am interested in or that I am committed to? It is a good exercise to do. Are you committed/interested in fitness, nutrition and diet, your work objectives, etc...? Are you committed to changing your life for the better?

And what's the difference?

In my experience, spending time on the things I am interested in are fun, but often lead to average results. I am interested in playing the guitar (for example). Am I committed to practicing my guitar skills every day for 2 hours? Maybe not. Ultimately, it is the slogging through the tough times that leads to above average results. Be it Work, Personal, Family. 

Most importantly, recognize the difference between the two.

But then again, what do I know? 

Carving this out of the side of a mountain, was that Interested or Committed?
