If you have that many clients and working around the clock like you said, why did you bump this thread? A day only has 24 hours, so you can't possibly work any more .
Joking aside, saying I am the best and nobody else is better than me makes you sound unprofessional. It creates the opposite effect of what you want to achieve.
Keeping your past work a secret is also not something that is normal. Those with something to show, like to show it to entice more clients.
