My brain is like my lawn mower

I used to think my brain is like my iPhone - I use it all day, then recharge it overnight while I sleep.
Today, I've decided it's more like my battery-powered lawn mower.
When the grass is short and dry:
the cutting is easy, and,
the battery lasts for up to an hour, and,
I happily mow all my lawns, in one go, and then I recharge it.
The recharge takes 2-3 hours.
When the grass is long, and lush:
the cutting is hard, and,
the battery lasts 20-30 minutes, so,
I have to mow my lawns over a few days, recharging each day.
My brain is like that.
And, henceforth, I've decided to stop beating myself up whenever I can't mow all the grass in one day! The grass is long and lush in my world!
How about you?
