Are you someone who tends to leave things to the last minute? Yeah, I know the feeling, it's not great right?
So why do this with your Mac (or tech in general). We need out tech and IT to work 100% of the time.
You may not believe it, but I would say 95% of the time, the work I do for my clients is always an urgent one, why?
Because out Macs/tech/IT is what we need to do out work. If it's not in good order, we can't work.
Think of a car engine without oil.
