The subject of success and I had one idea that came upon me and my late teens and I think it was most important idea that I've ever had and it was simply they said if you study successful people and you do what they do you'll be more successful And if you study unsuccessful people and you avoid doing what they do then you will not be a failure Is some of the principles that I've discovered over 20 years of research I have studied successful men and women I read biographies and autobiographies I have looked at the characteristics and principles of them I studied philosophy and economics and religion and psychology and metaphysics and I've come to 10k qualities Now there may be more than maybe less but I find that each of these 10 qualities that's successful men and women have that if you have these 10 qualities there's nothing in the world they can stop you from being an outstanding success So let's talk about these principles The first principles is clarity It means clarity of thinking it means thinking clearly and it extends from thinking clearly to a series of other things have or they have a very very limited sense of direction sometimes no sense of direction at all

Starting point with regard to clarity is to know where it is you're going and what it is you want to be and what it is you want to have and what is you want to do the second key with regard to clarity is decisiveness

And the habit of indecisiveness And what happens is we always have to work for people every single time if you know what it is you want to accomplish and the difference between successes and failures is not the successful people make right decisions you've got to have a dream if you want to make a dream come true have vision in the book of Solomon and when you see men and women who rise from poverty and obscurity to fame what they were When we were they don't turn us on is competence and this is a discovery that I made a couple of years ago and it just staggered me because I've been studying success for years refining excellence refining excellence Can I saw something that I hadn't noticed It's almost like something brought to the surface of can

Dear Aman,
Lets meet on Teams tomorrow. We would like to give you an environment where you can show us how you could build a page. Reply with your personal email address and we shall book a meeting with you shortly.

Good luck
