The method i used lol
1) Be a good servant and make sure your WT and pub are always underlined every meeting(great for appearances)
2) Comment every meeting(a "sure way" to know someones "spiritually qualified")
3) Average between 12-15 hours in Field Service(another "sure way")
4) Handle all your assignments aka company functions(carrying mics,stage, WT, talks, etc)
5) Be nice to the elders(kiss ass), let them know your always available for any extra company functions(this shows a "willing spirit")
6) Keep double life secret(in my case fooling around with other JW girls, who are all closet freaks btw i dont care how spiritual they look most are down to go to clubs, bars and do sexual things and still go out in service the next morning lol!)
and thats basically it lol thats how I became one
No actual christian spirituality, relationship with God or holy spirit required lol
