"I owed my accelerated career and successes to two things: hard work and luck...," the entrepreneur said.
Tony Elumelu, the chairperson of United Bank for Africa, said he became a bank chief executive at the age of 34, one of the youngest in the industry at that time, by a dint of hardwork and luck.
He was the CEO of the defunct Standard Bank at the time before a business combination with UBA saw him become the chief executive of the new larger entity.
"I owed my accelerated career and successes to two things: hard work and luck, and I know firsthand how these factors are inextricable in success," Mr Elumelu said in a Facebook post on Wednesday.
"My successes - and yes failures - have always driven me to create opportunities for young people. I believe that our young have the talent and the zeal to transform our world."
Mr Elumelu currently chairs Heirs Holdings, a family-owned investment holding company, and also Transnational Corporation of Nigeria, where he holds a 2.1 per cent stake. He has a 7 per cent interest in UBA also.
His philanthropic initiative Tony Elumelu Foundation empowers young entrepreneurs in Africa and has active presence in 54 African countries.
Mr Elumelu noted that the time he took the helm at Standard Bank coincided with a period of fast-paced transformation in banking when "reform-minded policymakers had opened up paths for consolidation and strengthening our sector".
He added that even though competition was stiff within the industry, being young posed no barrier.
The board of trustees of Tony Elumelu Foundation this month endorsed the appointment of a new CEO Somachi Chris-Asoluka, who is in her early 30s, a feat Mr Elumelu linked to unusual technical ability as well as leadership skills.
Mr Elumelu urged successful leaders to champion young people who are focused, hardworking and committed to making a difference in their communities, because their drive and determination make things happen.
"More than ever, all of us who have attained success must become role models for the younger generation, so that the next generation can learn from our mistakes and achieve even more than we have," he said.
"I believe that prioritising our youth - supporting their dreams and aspirations - is how we can create a sustainable future for the world.
"The greatest success in leadership is leaving a legacy and pathway for the next generation."
The UBA boss added that leaders must focus on long-term goals and succession planning to build a lasting legacy and ensure long-term success.
