First of all, be quiet (LOL), take a deep breath and think.. I will consult a financial advisor, pay off my debts, share my blessings with my relatives and closest friends.. invest, travel, give something to church/charity, build school, orphanage, scholarship, etc.
Like everyone else....pay off debts, set up my parents for life. Then, I would donate my current hobby farm to someone in need. I would build a horse rehab facility complete with a swimming pool for exercising. This facility would have the finest rehab vets, consultants, and massage therapists.
And there'd be a dolphin tank. I don't know why. Just thought it would be cool to have an underground riding arena where you could see dolphins swimming about.
