I can understand the differences of opinions, but some posters seem to cast their opinions and desires on what they think other people should do. Money shouldn't enter this discussion if you are referring to what other people do, as you don't know their financial situation. For some people, $350 is magazine money while for others, it's a car payment. When you balance purchasing an Apple Watch against purchasing magazines, it's easy to pick an Apple Watch. Conversely, when you balance purchasing an Apple Watch against making your car payment this month, it's easy to forego the Apple Watch.
The OP did what made him happy at the time, then later decided that he would be happier if he changed course. It's his money and his right to choose what to do with it.
