The more hectic things are, the more undisturbed you should be

In startup life, always follow the rule: “the more hectic things are, the more undisturbed you should be”
Maintaining a facade a calm whilst inwardly panicking is a skill that needs practice.
Never let your panic/stress/tension show.
It’s easier to think when you appear calm.
It’s easier for others to remain calm when you remain calm.
No matter the crisis, be cool.
