I read this recently, "If you can think, you can do anything." Simple enough, isn't it? Perhaps you'd want to tweak the sentence and add a few more words for clarity or for depth. Or maybe it works perfectly as it is.
I would like to take it further. If you can imagine it, you can create it. Especially today.
Now we live in a time where visual manifestation of ideas has become so much faster and easier. We've got films showing ideas that then influence science and engineering. We've got 3-d modeling that lets us prototype ideas fast and discard them just as quickly, allowing faster development at any time. Pretty amazing stuff, isn't it? So energizing too!
