The more things go wrong, the more you fall back on doing what you know. And you know accounting. So instead of becoming a better accounting manager, you focus on being the best accountant on the team. You start taking on more tasks that your team should be doing themselves. You withhold your feedback and concerns because you don’t want to demoralize people further. You rally the team by crying, “We’ll get through this! I’ll show you how it’s done! Just watch and follow me!” And that’s all it takes. That’s how normal, reasonable people turn into unbearable micromanagers.
