what will increase your odds of success is to work smarter and have better hourly output than your competition (whatever is appropriate measure of 'better' in your case). Working long hours should be your last resort not your first how to succeed. Yes I do understand that longer hours compensate lower hourly output but I would argue that you should find area where your talent lies. If you are in top 5% in given field that is enough competitive advantage without putting more then regular hours. IMNSHO Reason why most startups fail, there are not enough hours in a day to compensate for a lack of innate ability to do job.
