Certainly that is a most important element.

But I would think for many of us the requirements of day to day work and family don't leave us with as much time as we would like for things such as practice.

When I was single I went to the range once a week - then I got married to a wonderful lady who was a "package deal" with a sister, two daughters, two nieces and four grand-kids.

Free time? What's that. :)
