what is wrong with this pargraph
Since every person has only one opportunity to live each hour of his life, the time must be spent wisely. He should spend it thoughtfully. He should care what he does with his time. He should use good judgment. He should be intelligent in his choices. You never ought to waste time. It is too precious. You shouldn't waste electricity either. Turn out the lights when you leave a room. Money doesn't grow on trees. If it did, I'd get a money tree right now. I do have some money saved up, and when I get enough, I plan to buy a car. What I want is a '57 Chevy, two door. I saw one advertised the other day, but the guy wanted too much for it. I watch the ads in our paper every night. One day there will be a good buy. A friend of mine got a neat car that way. I wish I had his. I'd soup it up like nobody ever has. Dad would say "to fare thee well." That's the way he talks. He's a pretty neat guy. He works at U.S. Motors as a superintendent. They have a good plant there. Dad thinks that maybe I can get a job there this summer. If anybody can pull it off, he can. That would be spending my time wisely. Which is what life is all about. I'm going to a junior college in the fall. You can't spend time any wiser than that. Everybody knows that. Data Processing and Computer Technology, that's what I'm going to take. There's money in that. It's going nowhere but up. You've got to admit that's wise.
