A made up mind is hard to change (Jeff Bezos or Confucius, I don’t know who, but the phrase got stuck with me)
If you stand still, you fall behind. What worked yesterday might not work tomorrow. You have to adapt.
Guessing as a Strategy
Guessing gets a bad reputation. In technology, it is a requirement. You make predictions based on what you know. You experiment. You fail. You learn from the failure and guess better next time. The alternative is waiting for perfect information. Perfect information arrives too late.
Taking Risks
You have to take risks. A calculated risk compares potential failure against the cost of doing nothing. Doing nothing usually costs more in the long run.
The Challenge of Changing Minds
Resistance to change is the hardest problem. Once a team commits to a technology, they defend it. Showing them new facts rarely works. You have to show them working code. You have to prove the new way solves a problem they actually have. People do not change their minds because of arguments. They change their minds when the new reality is easier than the old one.
