In my twenties, I kept medical appointments in my head for me and both kids a year out. I never saw any point in jumping through hoops to put it in a calendar. It struck me as a pointless time waster to write things down that I was going to remember without writing it down -- and then have to also keep track of the calendar, check the calendar regularly, etc.
My messy stacks of papers made me look disorganized, but I could find anything important within ten minutes. In contrast, we routinely tore the house apart for an hour looking for something of my husband's.
He liked to organize and file and alphabetize. But the things he failed to organize often ended up in a heap on the floor. He did all that because he couldn't keep track of it mentally.
If your life works without checklists, don't worry about it. But if you find you start overlooking important details as you get older/busier/in a new and unfamiliar situation, you might revisit the idea.
Just don't rain on someone else's parade. Check lists work well for many situations and are especially valuable when lives are on the line for some reason (or similarly critical situations where mistakes often happen for various reasons).
Agreed, checklists can become a cargo cult. Also, checklists don't always need to be written down; just systematizing some mental checks can be helpful enough (e.g. "phone-keys-wallet").
I like to organise things in groups (for example, for paragliding I had 3 x 3 items, one for environment, equipment on the body, equipment "off" the body, respectively), or use mnemonics (before leaving plane: MaSeLToF (Main switch off, Sun guards set (and sun glasses removed from cockpit...), Logbook completed and hours noted, Tie down and chocks installed, Flight plan closed).
