Just to add......it can't be tricks. I get the sense you are still looking for a magic bullet. Hobbies and interests, etc. have to be things that you actually enjoy doing. If you are only doing them to win your wife back then you won't sustain it and eventually you will be back in the same boat.
Here is an example of something I attempted to do.
My XW loves to read so I thought it would be cool if I woke up every morning and started to read. She would see that I am trying to learn and grow, etc. She also likes to read so we could bond over it. Problem is that I hate f-ing reading and it was something I could not and did not sustain. It lasted for like a weak.
Do things that you enjoy because if you enjoy them they will more likely stick.
