People who give us "negative feedback" are a little like our dreams. Would you rather dream that you were swimming in a beautiful green-blue, transparent lagune with wonderful dolphins accompanying you in your movements forward or that you are being persued by Dorthey's Wicked Witch of the West in the Wizard of Oz? If these are workmates, ignore them and concentrate on going places after work where you can find people who share the things you love doing and with whom you'll have some common interests to share. If these are "friends" or former friends, you're running in the wrong crowd. In any case, people who need to judge others are really only transferring their own worries about themselves.
