Nigerian billionaire Aliko Dangote, known as Africas richest man, told a forum in Ivory Coast on Saturday how he once took $10 million in cash out of the bank just to look at it and get it into his head that this was real money, not just figures on paper.

When youre young your first million is important, but after, the numbers dont mean much, Dangote, a manufacturing tycoon with a range of companies spanning cement to flour, told the Mo Ibrahim forum in Abidjan.

One day, I cashed 10 million, put them in the boot of my car I put it in my room. I looked at them and thought now I believe I have money and took it back to the bank the next day, he told his audience.

Anecdotes aside, Dangote said that the two most promising sectors for Africas future were agriculture and new technologies. But he advised young African entrepreneurs not to get carried away by the first flush of success.

Often in Africa we spend our projected incomes. There are ups and downs in business, he warned.

Dangote said he regretted the customs and administrative problems that hamper business development throughout the continent.

As an example he cited the difficulties his cement group faces in exporting to Benin from Nigerian factories 40 kilometres (25 miles) from the border. Benin imported more expensive cement from China instead.
