Wanting to go back to serving, but having a difficult time making up my mind.

I served for a couple of years and loved it, but unfortunately ended up at a restaurant where my hours were drastically cut. I quit and got a job at a law firm working your normal 8-5 Monday-Friday schedule. I have a great boss and benefits. My issue is I can’t bring myself to love what I do like I did when I was serving. Serving gave me an adrenaline like no other. This job at the firm can be really stressful and I normally take it home with me. I am thinking about quitting and going back. I miss the flexibility in my schedule and the adrenaline but I have a more stable income at the firm. Idk what to do!
