Questions

I've had experiences with many different types of personalities and one thing I've learned is that almost everyone claims to want constructive criticism, but few people actually welcome it.

Example:
Whether it is a work project, art, a gift or something else along those lines; think of the last thing that you worked very hard on completing that you also believe was truly successful with zero to minimal errors.

Now, imagine that someone you don't personally know tells you this:
"These are the things that are good about what you did, these are the things that are bad about what you did and this is what I would do to make it better."

Remember, initially you thought it was great so there weren't any major flaws, yet here's someone that doesn't know exactly every detail of what you did, telling you that there are things that are wrong.

Please keep in mind that this is meant to be about the last thing that you completed that you are proud of. How would you handle the criticism that was provided?
