I got some positive things from my time (25 years) in the WT but at a very VERY high price.
Ability to talk to all sorts of people. Limited public speaking. Speaking my mind/thoughts (which was really regurgitation of THEIR thoughts).
Toastmasters, college, etc would have given the same - and better - training with much GREATER payoffs: Education, true marketable skills, honest self-esteem, better understanding and acceptance of myself thus putting me in a position to make better social connections.
I did not get married or have children of my own because I was putting kingdom interests first. I helped raise my younger siblings (even had legal custody for a time). I dated some wonderful worldly guys but had to break off relationship because of mandate to marry only in the lord.
I have managed to make a pretty nice life for myself but it's been a tougher struggle than it should have. Took me a while to wake up from the the FOG of JW-ism.
The time value of freedom and real world experience cannot be measured. Too high a price to have paid for being involved with the WTS at critical times in my life.
