Well, it's all really coming to light. This one might be a bit silly. But I've noticed that when I play video games (like the Sims 4, for example) I constantly start a new game with a poor Sim and have them work really hard toward riches... and once they are rich "enough," I stop playing because I find it boring.
Guess it's time to see having money as interesting and sexy instead of boring because the challenge is gone.
