As I observed myself it looks like I never stop on planning to buy new things that I dont have yet.
You are being tempted by those things. Don't compare of the things that you don't have. Don't focus on what others have. Appreciate even the smallest thing or happening that makes you happy. I also experience envy, and planning what things to buy. I'll return a question, What do you want to dohave when you get older? Me- it's simple to have ahouse to live,a garden, I want and I imagine my self planting flowers in my yard. Planting potatos and other root crops. But before that I want tp experience the trends in my younger years.
