I have a software business.

On business, if our software cannot provide enough additional value to customers, then the customers should use one of our competitors, and we'll move on to another market. On personal, I've sacrificed all the above as well, but I don't think of them. My customers are much more important to me.

If the 80+ hour weeks and extremely low pay are important decision points for you, then you should choose the high paying job.

I wish you all the best.
