I applaud your concerted efforts there.
My last 8 *years* in 'the truth' were barely going thru the motions. I finally stopped meetings, service, and talks. I've spent the last 11 years of my life feeling guilty for not wanting to be a witness and not feeling free to make my own decisions with my life.
I didn't fully fit in the witnesses, didn't really fit with my familyl, and certainly didn't fit in the world because I was still feeling under the influence of JW upbringing.
That's 19 years of limbo. Added to about 15 years actually trying to live up to my spiritual obligations.
I think if I had done like you did, Give it a go and keep my eyes open and my wits about me, I would have come to the same solid conclusion you did without wasting so much time.
You got things figured out by age 23? I humbly bow to your clarity of thought and careful, thorough consideration of options set before (and hidden from - !) you.
Impressive.
