My experience has been that my mind was so full of the jw stuff that until I was in a particular situation I wasn't even aware that that feeling existed. So I put myself in some of those situations so that I can prove to myself what is good or not.
Some examples: I went onto a military boat that asked you to salute the flag as you entered it. It was the first time I had saluted the flag. I thought it felt a little corny, but it was a jw 'hurdle' to get over.
Singing 'Happy Birthday'. That was a tough one. I had to work on that. I would sing it in the car to practice. Still feels wierd, but is it wrong? NO. So I put myself through it.
I stayed out of the hall for about a year. Then I went back to it to check it out and see what my opinions were of it. When I left and went to the grocery store old feelings of being isolated from the 'worldly people' crept in. I found that very strange. I never realized I had that feeling. Before going to the store I had felt very comfortable and I enjoyed those people. But after coming out of the hall, suddenly they all felt very wierd and worldly to me. Amazing!
I went to a Baptist church today for the first time to check 'em out. (I go to 2 community churches regularly) Suddenly those old prejudices came back. Didn't feel like praying with them because maybe they weren't praying to the same God I did. All those old little feelings.
I figure I need to experience things. That way I will be more well rounded out. Also, it will show up those dark looming thoughts that I am not aware of and I can work at getting rid of them. Then I will be happier!
Hope that helps.
