I for one take a lot of my JW teachings to heart.
As with all mythologies including the bible, there are central themes present throughout, and usually for the benefit of civilisation.
A brief list of things I was raised to do/believe/etc (its hard to say what my mother would have taught me without the JWs though): Honesty, Respect for others, Not seeking money as the prime directive, Patience (god did we ever need that!). I'm glad I can use these learned behaviours when they benefit me. I can also take them off now without feeling guilty (i.e. white lies to make people feel better, although I'm still usually brutally honest even when I don't have to be, just because that's the way my personality developed, it's an ingrained habit now; Now I can lie to the authorities when I feel I should without feeling guilty, there are things that the government shouldn't need to know about the citizenry; etc)
I have found it easy to reject everything that the WT taught. That was never a problem. My problem is the regret I felt in believing. I've learned now that regret is essentially a useless emotion. Making a mental note of beneficial teachings was good for me, it might piss others off though.
