Repeat after me...You do not have to suffer to build a business. So many stories like this are sensationalized in the media and it convinces so many young entrepreneurs that it's a right of passage to struggle while building a business. It's not true. Yes, other entrepreneurs had determination and some sacrifice...but they most likely didn't suffer so dramatically, nor make their loved ones suffer along with them. Don't fall for the trap. Be smart enough to build a business without the struggle.
Capitalism says that in order to improve your life you must first improve the lives of others. The more lives you improve, the better your life will become. If you eliminate your own self interest of a good life, you have forgotten the biggest reason you are building a product in the first place. You aren't respecting your life, your wife, your business or your customers by doing this.
Stop struggling and build something valuable that people will pay you for. Living out of a van down by the river may get you a few news articles and motivational speaking gigs, but your struggle is not related to your success. I've been there...I've done it. It is irrelevant and unnecessary.
