Rewards

Does anyone else do rewards? A friend recommended it to me and it’s actually worked really well. I’m trying to cut down on my wine so she and I sat down and I bought some things from a lab amazing craft sale. They arrived wrapped and I can’t unwrap them until I got certain milestones. 1 day, 3 days, 5 days etc. It’s a grab bag so I never know what I might get. I’m wearing my 5 day earrings and every time I see them I smile. Last night I was tempted but I remembered I wanted to see what I got this morning. I’d love to know if anyone does something similar and what you use as “rewards”.
