“We so often get pulled into tasks that we should, by rights, be asking others to help with. We tell ourselves that they’re not quite as experienced or knowledgeable as us, or that it will be quicker if we just do it ourselves. But there’s a massive cost to this way of thinking. By being unwilling to delegate tasks that others could reasonably help with, we fail to make progress on the important or tricky things that only we can do.”
