In his 2012 state of the union address, president barack obama said:
"nowhere is the promise of innovation greater than in american-made energy. we've opened millions of new acres for oil and gas exploration, and more than 75% of our potential offshore oil and gas resources. right now, american oil production is the highest that it's been in 8 years. last year, we relied less on foreign oil than in any of the past 16 years.
but with only 2% of the world's oil reserves, oil isn't enough. this country needs an all-out, all-of-the-above strategy that develops every available source of american energy—a strategy that's cleaner, cheaper, and full of new jobs."

Read this excerpt from i never had it made. "it's all that ought to count," he replied. "but it isn't. maybe one of these days it will be all that counts. that is one of the reasons i've got you here, robinson. if you're a good enough man, we can make this a start in the right direction. but let me tell you, it's going to take an awful lot of courage." he was back to the crossroads question that made me start to get angry minutes earlier. he asked it slowly and with great care. "have you got the guts to play the game no matter what happens? " "i think i can play the game, mr. rickey," i said. the next few minutes were tough. branch rickey had to make absolutely sure that i knew what i would face. beanballs would be thrown at me. i would be called the kind of names which would hurt and infuriate any man. i would be physically attacked. could i take all of this and control my temper, remain steadfastly loyal to our ultimate aim? which is the central idea of this excerpt?
