As someone with a semi-nomadic lifestyle, I've gotten used to live off a suitcase.
Instead of organizing my gear on shelves and drawers, I keep all my cameras, lenses and accessories in my bag. Having a limited space to store my stuff makes be very selective about what I buy: a new item usually means another one has to go.
But the reason why I always keep my gear in my bag is because that way I'm always ready to go. If I see fog in the morning, I grab my bag and get out. If the Spanish government establishes a mandatory quarantine, I grab my bag and go to my parents' farm to spend the lockdown there.
I know I won't be forgetting anything because all the gear I'd ever need is there, and ready.
