Mistakes are often frowned upon in modern society. However, mistakes are an integral part of the human learning process.
If you notice toddlers and babies, they often try to smash several objects they found, to find out what happens if they do it. Often breaking things in the process. For example, moving a glass on the table, causing it to fall to the floor, they figure out that it breaks and produces sound. They discovered physics and acoustics, they just don't know yet what it is called.
Humans were born scientists, we are curious and passionate about gaining knowledge. Making mistakes is part of this process and should not be frowned upon. We just need to ensure we manage the risks associated with these mistakes and like any other experiment, ensure the safety of people around it including yourself.
In the context of relationships, we often hear the saying "Women is always right". This is in terms of making decisions in household details, finance, and raising the children. More often than not, that is true - women will always go for the best option possible, and they make a substantial amount of effort to get things right the first time. Ensuring it is aligned with what other parents do, given the situation at hand.
But it begs the question - does everything need to be always right? How does it affect the learning process of the family members, if the correct options are laid out for them?
