Like Flipper has posted, you need to fill the void.
As a JW your life revolved around meetings, field service, personal study etc. That amounted to a good few hours each week.
What I did to fill the void was pursue interests. In my case I studied higher education and obtained Chartered membership of my profession. I also enjoy music and play guitar, and enjoy local sightseeing. After work, weather permitting, my wife and I go for walks to keep fit and usually stop off for a coffee at a local cafe on the way back.
