With money you can make yourself sad, so why spend money so happily?

Have you ever made a decision of buying something you regret in life? Having a job and a steady salary, I feel like even weighing out my options I still will think otherwise about that phone I just bought for my mom which is a different brand from the usual she uses. Because I know I'm going to hear her complain until she wants her old phone back. You think I spent money on GIVING her the phone happy? Think again.
