I’ve never been able to. I’ve tried:

Keeping receipts, text file on laptop, trying to keep track… too absent minded. Forget one receipt, it’s all off.

Bank app on phone? Phone stolen last year, wary.

Weekly visit to atm to check balance? Forget pin, can’t remember, locked out of account.

Paying for everything with cash might work, but unsafe neighborhood. And I forget where cash is, random $20 bills found in bizarre locations months later.

At my wit’s end. Any adhd people experience similar?
