If it was me, then I will pay my family's debt, will put up a business, will share it to my siblings, other relatives, I will also share it to charities such as in the orphanage, home for the aged, more likely to those people in need. Yes, of course the rest of the money will be save for future plans.
Yes, I'm not selfish. I really want to give a hand to those people who are in need, and that's included in my dream. It's a great feeling if you could see the smiles of the people that you know you have done something good to them.
