Always question whatever you do, actions with good intentions can cause something dangerous, unpleasant or inconvenient to happen. Accept that we all make mistakes but most importantly, learn and never repeat them.

See someone make a mistake? Worst thing you could do is express anger or frustration to others. It leaves you embarrassed, shameful and bitter. Keep calm and ask yourself and others "Anything you could have done to prevent this mistake?".

Be a part of the solution, not the problem.
