Three decades of learning
I’ve learned great many things over the many years I lived on this planet. Here are a few:
I learned that most people are not that bright. Average is boring. To always be calm. Never curse in written or in person. One can save lots of time by just refraining from arguing with people that don’t matter. Don’t be late to meetings. Be respectful to everyone regardless of their appearance or occupation, with interaction some people will lose their initial level of respect and some will gain.
