Why the urgency to preach?
Just like you were 'wrong' about God when you were a JW, you could be 'wrong' right now. Right?
Why not take a little time (years) to sort things out. The world is a big place, with many competing ideas. You're not expected to have it all figured out.
Focus on your family. Worry about "religion" and preaching later. You only get one shot at some of this.
