Most nights, I get less than six hours of sleep (though it's recently improved)

I have little to no social life

It's been like this for five years

If you want something, you have to work for it

After I embraced these eight rules, my life became much more productive:

1. Hard work, discipline, and consistency – all you need to succeed

2. You can have anything you want, if you really want it

3. Surround yourself with people smarter than you

4. Self-belief is your biggest secret weapon

5. Nobody owes you anything

6. The world isn’t against you

7. Listen more, talk less

8. Never quit
