WHEN LUCK FAILS
We tend to believe that good or bad luck happens for a reason. So whenever you're successful, you just 'got lucky' or, when your business isn't doing too well, you're simply out of luck.
Well, I think that concept is too uncertain to count on. So, let's not count on it at all.
Let's count on solid work and data-driven design. That way, you'll never be stuck on luck.
