I think it's a great tool to master as it can be quite challenging at times when you really want something, and someone else has it! For instance, there there was this whale who was talking about steemit the other day. He just joined and threw 15k on here. Immediately was an influencer on here and I noticed that I was feeling frustrated about. When I realized my frustration I asked myself, "what can I appreciate about this person?" and then I just went into this rampage of appreciation which left me feeling super inspired and appreciative of this person. It really flipped the script for me and that's a powerful thing to do!
