If I didn't have to work, I'd spend as much time as possible with my kitties. Afterall, they are my babies. I miss them during the day while at work. I suppose it feels similar to mothers missing their children while they work.
If I didn't have to work, I'd look for a meaningful non-profit organization to volunteer for. If I didn't have to work, that would mean I don't have to worry about money so that means I can try to make a difference in this world without concerning about my own survival first.
I wish I didn't have to work, so I can do what I want, when I want and not worry about anything (other than my fur babies) at all.
