Spread the word- except maybe remove the word "grind" from your vocabulary!, working at a computer on a desk beats doing manual labor or repetitive assembly line work... that's a real grind. There is nothing like having that work ethic like you describe- most people can't hack it and work 14-16 hour days, and do outbound sales calling and marketing- you've got it- keep it up. If someone can work 8 hours then come home and find domains and jump start their business- I really applaud that. It's great to see your story and young people like yourselves full of enthusiasm and drive as the news media likes to report otherwise that "Millennials" have this reputation for entitlement and expecting "free stuff". The best investment you make is in yourself and your self-education, taking risks and coming up with new ideas. The web is full of opportunities to find new business ideas.
The world needs many more of you- those that don't work under the security blanket of large corporations but rather be independent and young entrepreneurs and creating small business' to keep the world functional, innovating and operating.
