How do I carry the weight of numbers that decide a company's survival?

You can reserve for anything and defend it. And underneath the skill sits a real weight: the numbers you set quietly hold up whether a company lives or fails, and few around you fully grasp that. Feeling that weight is not a burden to fix. It is the proper seriousness of someone who understands what their work actually does. But carry the weight in its right size. You are responsible for sound numbers, honestly reached, from the best information you have. You are not responsible for every force that could sink a company, most of which are far outside your desk. When you let your reserves stand for the whole fate of the business, you take on a load that was never only yours to hold. Do the work carefully, document your reasoning, and then let the numbers be what they are: your honest best, not a prophecy. At the end of the day, set them down. You have given the company sound figures to steer by. Steering the ship is many hands' work, not yours alone.
