Security Questions

Security questions baffle me. I don't know the answer to any of these questions, especially an answer that I could be sure I would always remember.

What is your favorite sea animal?

What was your least favorite fruit or vegetable as a child?

During what month did you first meet your spouse or significant other?

What is your favorite warm-weather activity?

Who is your favorite artist?

What was the first major city you ever visited?

What is your favorite type of music?

What is your favorite type of vacation?

I ultimately did guess at some of these, but I'm not convinced I'll be able to remember my guesses. When I tried to log back in, it said:
