One of the things exxers tend to feel bitter about is the loss of time due to the years they spent in the WTS. Why continue to spend time being bitter about them? Let the WTS go. If you don't, you're still letting it run your life. Focus on something else, like the other exxers in this forum, or on the things you want to do now.
Remember, you are who are in part because of that time. Writers must be willing to throw out sections of prose--even entire paragraphs of a novel--if it makes the story better. They must also learn that those hours of work weren't wasted; they were necessary to make the final product even better. Likewise, your time in the WTS wasn't truly wasted. It helped make you who you are. Hey, without it, a JW might come to your door and convert you this very day, forcing you to waste the rest of your life. Now, you're too smart for that.
That's how I look at it, at least.
