Productivity tip #17 is to focus on what you can get out of any given situation. Don’t worry about the other party.
In fact, if someone else can benefit from something, that’s actually a bad thing and you should only do stuff when it benefits you and only you.
You don’t believe you get better by building the biggest building in town. You think you get better by cutting down any towers bigger than you now.
All the benefit is for you and its practically your duty to ensure nobody around you benefits at all.
