"This isn't something we have to accept," Romney told the Republican National Convention, adding that "now is the moment when we can stand up and say, 'I'm an American. I make my destiny. And we deserve better!' "
He went on to ask Americans if they still felt the excitement from when they voted for Barack Obama four years ago, saying "there's something wrong with the kind of job he's done as president when the best feeling you had was the day you voted for him."
"The time has come for us to put the disappointments of the last four years behind us" by electing him president, he said, adding that "many Americans have given up on this president but they haven't ever thought about giving up - not on themselves, not on each other and not on America."
The country's needs are not complicated or profound, he continued, telling the RNC that "what America needs is jobs, lots of jobs."
Americans "who now believe that the future will not be better than the past" will be correct if President Barack Obama gets re-elected, he said, and outlined his five-step plan that he says will create 12 million jobs, calling for increased domestic energy development, education reforms, new trade agreements, deficit reduction and easing taxes and regulations on small businesses.
Romney promised to bring a better future for America if elected president, telling the RNC that "our children deserve it, our nation depends upon it, the peace and freedom of the world require it."
