Sometimes we fall, sometimes we stumble, but we can't stay down. We can't allow life to beat us down. Everything happens for a reason, and it builds character in us, and it tells us what we are about and how strong we really are when we didn't think we could be that strong.
We may stumble and fall but shall rise again; it should be enough if we did not run away from the battle.
Companies that grow for the sake of growth or that expand into areas outside their core business strategy often stumble. On the other hand, companies that build scale for the benefit of their customers and shareholders more often succeed over time.
Keep on going and the chances are you will stumble on something, perhaps when you are least expecting it. I have never heard of anyone stumbling on something sitting down.
You don't stumble upon your heritage. It's there, just waiting to be explored and shared.
