If you look after your staff, they'll look after your customers. It's that simple.

Listen more than you talk. Nobody learned anything by hearing themselves speak.

If somebody offers you an amazing opportunity but you are not sure you can do it, say yes-then learn how to do it later!

Never take your eyes off the cash flow because it's the life blood of business.

If people aren't calling you crazy, you aren't thinking big enough.

I have worked like a galley slave throughout these eight years, morning till night, and I have given all I could to this work. I am happy with the results.
