“What comes easily to you that others seem to admire?”
Probably the thing that people admire, or are at least somewhat surprised by, is my ability to do pretty much anything on the computer. It started when I was a kid, with my Commodore VIC-20 and C64 computers, and it has just continued on through today. 
It happens pretty regularly, whether I’m editing photos for someone, designing a web site for someone from scratch, creating 3D anaglyph images, making changes to my own site, editing video for uploading to YouTube or burning to DVD, or even rebuilding computers from the ground up… people watching me often ask, “How did you learn how to do that?” 
My answer almost always is “I’m not sure… I just know.”
