Sometimes it won’t go the way you intend it. Sometimes you’ll make a mistake (or three). You’ll miss a deadline, you’re overestimate or under-deliver. There are a thousand-and-one ways to screw up. And at some point you’ll make that misstep.
But, it’s okay. It happens. More often than not it’s a revoverable misstep, and if it isn’t – it’s not the end of the world. No one has screwed up so badly that the world ceased to exist, because we are still here.
So let it go. Move on. It’s okay. There’s always tomorrow.
