"Regrets ? I've had a few, but then again too few to mention" (Who said that? ...ole Blue Eyes)
In truth there are too many regrets but as Blondie and others say, its no good looking back - except to warn the others. There is a new generation of young dubs who are not taught the truthful past of the Borg. So lets see..
I regret not realising a couple of fundamental truths . 1) That life is short and you have to plan to get something out of it in 70 years or so. When you believe that life will be eternal and you live for the future, you shelve the present problems and put up with it, just leave everything to Jehovah, and He will look after you in the long term. So you go on fro day to day , on the treadmill of Meetings/Service/Meetings and the life decisions that should have been taken are just ignored. Until one day you wake up and realize that the threescore years and ten are well along and you're in a groove that is by now a deep trench ..2) That Nothing in Life is likely to change unless YOU change it....
And BTW I regret once, many years ago,not gong to an Ike & Tina Turner concert because I had "feelings" for Tina and I thought it was untheocratic !
