Let me set the ball rolling with this:
The first thing President Yar'Adua should do as a national leader would be to forget that he's a leader and to think of himself as one of the rank and file of the people. Thus he should purge his mind of all vain thoughts and fill it with pure thoughts of service to his fellow-countrymen. That is to say, he should be a leader to serve the people in all humility to the best of his ability and not to lord it over them as their master and tyrant.
Generally a leader demands of his people implicit obedience to his will. But he should be a leader with a difference. He should not enslave his followers and enforce their blind obedience to him . He should partly lead and partly follow his co-citizens.
Very often, a leader imposes his whims upon his followers and makes them the instrument for the realization of his own ambition. But I think Yar'Adua would not do so. He should try to be an embodiment of the cherished and deep-seated ambitions and aspirations of the masses
It should always be his endeavor to uplift the suffering masses to his own level of culture and competency. He should continue as a leader only as long as the people wanted him; and he should readily vacate the place of honour as soon as he heard the smallest whisper of discontent among the Nigerian people.
