Calm and collected at the end of a quick visit to Islamabad, where he addressed a hot and sweaty hotel meeting room packed with businessmen, the 63-year-old former prime minister presents himself as a statesman-in-waiting.
"Our people are very excited. They are waiting for a response from the field and things look good. They, in fact, look better than what they were in 1997," he told AFP, referring to the landslide that last swept him into power.
Businessmen and industrialists traditionally regard Sharif's Pakistan Muslim League-N party as better on the economy than the outgoing Pakistan People's Party (PPP) and he comes back, time and again, to stressing his economic credentials for the May 11 election.
He won admiration for turning Pakistan into a nuclear power in 1998 and for building a high-speed motorway from the northwestern city of Peshawar to Lahore, his home town and Pakistan's cultural capital on the Indian border.
As the scion of one of Pakistan's richest families, in the early 1990s he privatised much of the industry that the PPP had nationalised.
He said he would forge a national consensus to fix Pakistan's crippling power crisis and repair its faltering economy, albeit without mentioning any details that might expose the limits of his promises.
"The problems of this country are gigantic. You've got to fix the problem of power, that should be the first priority. It needs a lot of resources, hard work and the right policy," Sharif said in an interview in the VIP lounge of Islamabad airport.
"About three to five years" is all that is required, he says, to fix the energy shortages which hammer businesses and make life a misery for millions.
Pakistan does not produce enough power to meet demand, and the government routinely fails to pay for the electricity it does consume. Power companies in turn cannot pay their own bills, and so supply cuts out.
But for all his promises of rapid and effective change, Sharif is no stranger to allegations of incompetence and graft.
He was first elected in 1990 but sacked three years later on corruption charges. His second term from 1997 to 1999 ended in a military coup by General Pervez Musharraf, which the public widely welcomed at the time.
Thirteen years after Sharif was sentenced to life in prison for hijacking, attempted murder and other charges, he says he forgives Musharraf, who now languishes under house arrest after a spell in self-imposed exile.
The interim government last month refused to put Musharraf on trial for treason, saying it was up only to the next elected administration. But Sharif ducked a question when asked what he would do.
"It's up to the courts... I've no personal vendetta against General Musharraf. If there was, I forgive," he said as he prepared to board a private jet to address a campaign rally in his Punjab political heartland.
Sharif has been criticised for being soft on Islamist militant groups. Asked about Taliban attacks targeting parties in the outgoing government, he stopped short of condemning the insurgents by name.
"Well it's very unfortunate. I've extended my sympathies and condolences to all these people and I appreciate their statement that no matter what, elections must be held on time," he said.
Like cricket legend Imran Khan, the only other party leader to address major rallies on a daily basis, Sharif has refused to shield himself behind bullet-proof glass when addressing the crowds.
"The danger is there and one cannot ignore that. But in order to establish eye to eye contact with the people, to have that kind of communication with the people I think it is necessary there is no barrier," he said.
He also bats aside perceptions that he and his conservative PML-N party are less trusted in Western capitals than the PPP.
"We had very good relations with everybody in the world and Pakistan was progressing, Pakistan's economy was thriving. We were number one in fact, what I want to say is we were the leading nation in South Asia," he said.
Analysts consider the only bar to a Sharif premiership to be Khan, whose call for change and reform has resonated with the urban middle class despite the fact that he has previously only won one seat in parliament.
Sharif declined to criticise Khan but was biting about the PPP, which won elections last time round in 2008.
"Their performance is zero, so they don't have anything to tell the people, they don't have anything to sell to the people of Pakistan because they didn't do anything in the five years," he said.
