This or that?

There was an article titled - What may have been by Gary Hayden in this week's 'Mind your Body'. Was an apt and interesting read.

Excerpt taken from his article,
'It is a sobering truth that almost every decision we make closes more doors than it opens...Every decision brings with it the very real possibility of regret.'

He also quoted Søren Kirkegaard, a Danish philosopher. (This is a good one)

'I see it all perfectly; there are two possible situations - one can either do this or that. My honest opinion and friendly advice is this: do it and do not do it - you will regret both.'

It got me to thinking that the question would now then be how much more will you regret if you did rather than did not do. And how do you know unless you did? ;)
