regularly deposit money into a savings account i don't have easy access to

I intentionally set up this account without an ATM card or cheque book, so that the funds are hard to access (I’m too lazy to walk all the way to the credit union and too impatient to wait in line, unless I really have to). So money goes onto the account every month, but it doesn’t come off. There’s only been one withdrawal in the past 6 years, and that was administration fees for a special statement the credit union had to generate for me. This has helped me to build up a nice little nest egg/emergency fund/whatever you want to call it, which just keeps growing. Very gratifying and definitely worth it.
