Things that waste time
1. Worrying what others think
2. Talking with people you don't enjoy talking to
3. A job you hate
4. Getting drunk several times per week
5. Doing a huge number of exercises at the gym
6. Returning something you bought or was offered to you
7. Overthinking what to watch
8. Going shopping when you don't particularly enjoy it
9. Staying until the end of a show that you're not enjoying
My girlfriend and I went to the theater and bailed after 30 minutes. I thought it was incredibly boring and pretentious. Some people might think it's rude, but life is short. I understand if somebody wants to leave while I'm doing stand up.
10. Not having a system to be organized and enhance productivity
However, I also don't want to fall into productivity obsession.
