There’s a lot, but here’s a couple important ones for me.

Do it right the first time, and it’s better to make a mistake than to do nothing at all.

These mostly apply to a work environment, but can apply to real life situations too. Doing these two things will drastically reduce the amount of time you have to repeat something or be called out for lack of action.

Nothing makes me more frustrated than having to redo something or constantly follow up on something because it was never done. Time is a finite resource. Don’t waste it
