Since I started swimming seriously as a teenager I’ve been going to the gym. 99% of the time the gym attendants would sit at their desk, usually watching the tv in the corner. I’d see people doing their exercises, often with bad technique, which at best reduces the impact of their work, at worst could cause injury. Very seldom did the attendants ever come over and offer assistance or advice to the people with less experience than themselves.
It seems much the same in business. People may look at others, be they colleagues or customers, and see them making potential mistakes but so often will refrain from suggesting potential alternatives, instead sticking to the bare minimum, until of course things break down and everyone becomes stressed as a result.
If this describes you then make today day zero. From this point on, if you see something that you feel could be done better don’t wait passively for things to break before you raise your concerns. Be proactive and make sure things are right from the off.
