Personally, I realized over the years that knowing and being able are two different things. Many people know how to do it, but very few do.
And one more thing: in one wise book it is said: "Faith without work is dead" ...
Therefore, I completely agree with the conclusions given in the post.
This is always one of my favorite lessons I tell myself and always will be. Knowing is not doing.
This is an interesting quote. I am guessing it comes from a religious perspective, but I would substitute faith for "desire" for many people these days. They want, but won't do the work to have.
