Simple solution:
- do not encrypt wallet.
- write down your password on a piece of paper and hide it somewhere safe. (uh another problem, he cannot remember where did he kept the paper)
- have password hints
- use all the letters in the alphabet as password or use your name in reverse as a password.
It is not a secure solution ,you must always encrypt your wallet but you can always save your password and pass phrase in a note pad which is not that difficult and keep in a safe location,never use password hints and easy ones since you are dealing with money and make sure you put in a very good password so that no one is able to crack it easily.
