You have just inherited $100,000. How you got it is of no consequence. Just be glad it came to you.
You have always wanted to start your own business and now that you have a little capital, it's time to get started. Tell us all about the business you will open. How are you going to start it, what will you do first, how do you propose to get customers (buy them, threaten them, market to them, etc.)?
Be as creative as possible. Go beyond the extreme. Call upon your imagination for this. Don't give us the boring "I started a business and advertised and they came."
Perhaps you were ruthless and bought someone out, or paid someone hush money, or bribed some county officials to help you. Perhaps you started a telethon to raise funds for your charitable business. Perhaps you bought a blimp and sailed around the country peddling your services. The sky is the limit here.
