Making Predictions, Even When Wrong, Is Better Than Not Making Any.

"Start making predictions in writing. You don't have to share them in public, but the habit will push you to understand your instincts and to sharpen your ability to see what works (and what doesn't) without the easy out of having to explain what already happened." - Seth Godin, Are You A Scientist?

Making the right predictions are really hard but not impossible to do. All you have to do is to do it often

Even better than to just making predictions about who'll be the winner is to do as many projects as you can.
