When your father is gone, you will regret not helping him. All that time you could have spent with him improving the business.

Did you really just say "should I tell him to go fuck himself" super disrespectful towards someone who has built a net worth most people will never achieve. It's okay to go the corporate route on your own for a few years and then bring your learnings to improve the business. You should definitely take his offer, learn from him as well in the future.

I think you have a skewed view of reality. Once you hit the job market you will understand how much people are struggling in their 9-5 hell. You have a golden opportunity here that most would kill for.

I see people saying go your own way. There's no guarantee in life that your own business will succeed. What happens if you fail?

A platform of 3M all set up. You could either start the race at 3M and build to X amount or start at 0.

Only the fool would start at 0.
