Great post! Just for me. I store the key on my computer and on e-mail, I worry that I will be stolen. I took and changed 4 symbols. I'm sure I will not forget them. The problem with anxiety is solved.
The even better solution would be to think a new dictionary for your words and to change each alphabet letter with the different one. Afcorsee, to do that you must write your own alphabet on a piece of the paper (stay away from the computer and internet).
This piece of paper must be stored like your precious jewelry because if lost and you don't have and photo memory you can as well say only to your wallet. There are many ways which the users which don't own the hardware wallet are keeping their private keys anonymous.
Different solutions are welcome and I hope someone will provide the even better solution to the thread.
