I simply replied, “Don’t let the sunk costs get in the way of deciding what’s best for the business.
Whenever sunk costs are influencing decisions, I always recommend coming back to this question: ‘what’s best for the company going forward?
If I don’t step up in times of need, I’ll eventually develop a bad reputation and founders won’t want to work with me.
If you just focus on what’s best for the company in the long-term you can’t go wrong.
