I take a long time putting my 아이디 together. I try to make it easy to get used to, I make sure it fits me correctly, and that the user name makes sense in the website I'm applying it to o at least fits it correctly. If 당신 don't want to take up all of that time 당신 can just write it on a piece of paper and keep it where it's 안전한, 안전 with your password.
