When starting a business, you will make mistakes and you need someone who can call you on your bullshit while still remaining true to the partnership. You want to have a partner who will not always follow you. It will feel easier to be with people who always agree with your opinion. However, in the long term it will create a culture of conformance and essentially destroy innovation before it started. Especially in challenging times, you need a partner that will bring a different angle or approach as you work together to find a solution.
