Nobody's born with an instruction manual for life. Despite all the helpful advice from parents, teachers and elders, each of us must make our own way in the world, doing the best we can and quite often getting things wrong. Messing up a few times isn't that big a deal. But if you get scared and try to avoid mistakes by sticking with just a few "tried and true" behaviors, you'll miss out on most opportunities. Lots of people who suffer from boredom at work are doing it to themselves. They're bored and frustrated because they choose to be. They're stuck in ruts they've dug for themselves while trying to avoid making mistakes. People who never make mistakes, never make anything else either.
I can't put my finger on it.
