Defintely go for it! my DH (and I) just opened a CrossFit gym. He LOVES it!!!! And left a very lucrative job in sales to do it. I am still in corporate america and it is driving me insane. He probably works harder than I do, but he is happy, and i am a basket case!!! ALWAYS pursue what you love. On their death bed, no one ever said that they wished they would have spent more time in the office. Carpe Diem!!
As for ramen, we got engaged, planned a wedding, moved in together, and opened a business in the last two months of the year - and we are more than fine! Are their sacrafices? Definitely. Are we eating out every day any more? No. And because owing your own business means no paid days off (at first) we have not taken our honeymoon yet, but happiness is worth it 100 times over.
PS - random - did you go to Notre Dame??
