Probably the most telling way is for each individual
to judge for themselves the results of any particular
activity.

What did it do for me, would I do it again?

In some instances depending on the people involved,
pushing that envelope can be somewhat cathartic.

It often helps to expand your horizons to truly know how far
you're willing to go and if it's something that makes you go
damn, I should have tried this sooner.

For me I like taking things to the edge, maybe tipping the
scale so I'm just over the edge from time to time. Doing
so but still maintaining a sense of what's what and keeping
in mind the other person and our personal safety.

If a person is able to reach out a little to understand
themselves better than I think something important has
been achieved.

It helps even more to know you have someone there with you.

That when you do want to go beyond, reach new heights, that
there is someone there to catch you before you fall.
