Being totally right at “something” you’re knowledgeable about is very difficult, even if you have experience. Your chances of getting it partially right are good, but being totally right is always next to impossible.
At the same time, being totally wrong at “something” you know well is also very unlikely.
The less knowledge and experience you have of that “something,” the higher the chances are that you’ll get it wrong . . . but again, getting it totally wrong is close to impossible.
If you’re waiting to get it totally right, then you’re in a never-ending game. You’ll always be a bystander—waiting, waiting, and waiting some more. . . .
If you want to have a real stake in doing “something,” the best possible chance at getting it right is by getting comfortable being in between totally right and totally wrong.
Then, work your way through the middle to get as close as possible to the totally right.
