(CNN) - In an opinion piece published Thursday evening, the presumed GOP presidential candidate touted lessons gleaned during his time heading the private equity firm Bain Capital as having prepared him to handle the presidency.
"The lessons I learned over my 15 years at Bain Capital were valuable in helping me turn around the 2002 Winter Olympics in Salt Lake City," he wrote in the op-ed, which was published to the website of The Wall Street Journal.

"They also helped me as governor of Massachusetts to turn a budget deficit into a surplus and reduce our unemployment rate to 4.7%. The lessons from that time would help me as president to fix our economy, create jobs and get things done in Washington."
Citing the Republican challenger's work at the firm, President Barack Obama's campaign has bludgeoned Romney in ads, on the stump, and in campaign conference calls organized for reporters. At the height of the attacks, Obama's deputy campaign manager cited financial documents from the company and said Romney had either committed a felony or was lying.
Some Democrats, however, have questioned the strategy of criticizing Romney's business record, or at least leveled lighter criticism. Former President Bill Clinton, who has described Romney's business career as "sterling," said that experience may not help the candidate come November.
But Romney said it had prepared him for the kind of work he may face if elected to the White House.
Citing his experience working with a steel company, Romney said he learned lessons about manufacturing and international business.
"First, innovation is essential to the competitiveness of U.S. manufacturing," he said. "We are the most innovative, entrepreneurial nation in the world. To maintain that lead, we must give people the skills to succeed. My plan for a stronger middle class includes policies to give every family access to great schools and quality teachers, to improve access to higher education, and to attract and retain the best talent from around the world."
In the piece, Romney also advocated for a "level playing field in international trade" and said that, "As president, I will challenge unfair trade practices that are harming American workers."
He said that his experience has taught him to handle a problem by "run[ning] toward it or it will only get worse."
"That will be my approach to our federal budget problem," Romney wrote. "I am committed to capping federal spending below 20% of GDP and reducing nondefense discretionary spending by 5%.
"This will surely result in much wailing and gnashing of teeth in Washington," he continued. "But a failure of leadership has created our debt crisis, and ducking responsibility will only cripple the economy and smother opportunity for our children and grandchildren."
Romney also wrote that he learned about "how energy costs impact the ability of a business to grow." On Thursday, he laid out a plan for the United States to achieve energy independence by 2020.
In his op-ed, Romney pledged that, as president, he would put his business experience "to work, to get our economy back on track, create jobs, strengthen the middle class and lay the groundwork for America's increased competitiveness in the world."
Romney and his running mate, House Budget Committee Chairman Paul Ryan, will campaign Friday in Michigan.
