Don't let someone tell you your dream is silly. What you may want to do could be unconventional, out of the ordinary, or just plain weird. But it's not silly unless you never dare to chase it down.
A lot of people would deem Mike Mika's dream silly. Why would someone want to reprogram the Donkey Kong video game so that the princess rescued Mario instead of the other way around? And why would an accomplished programmer like him want to spend time doing this?
His three-year old daughter asked why she couldn't play the game as the princess. Mike didn't have a good answer. So, he got to work.
Many of our dreams are borne out of our love for others. How could that be silly?
