Tempted to Give Up on Dreams for Gas Prices

I have been tempted to give up on dreams because of gas prices. So I got a hold of a book called 20 Dollar Gasoline--read it if you are okay with taking Prozac after: It’s tough. It is similar to all the doomsday books that seem to be popular about humans destroying the world and the human race. I try to limit the amount of books I read that are similar in nature. But because I am such a penny pincher I hate watching gas prices rise more than normal. So I read the book and could not put it down. He goes through in two dollar increments as gas prices go up, which they will go up, and explains what will happen at each increment. At six dollars a gallon everyone will abandon SUV’s. At eight dollars the airline industry will crash. At ten dollars SUV’s will go extinct along with recreational trucks (ones that do not serve a vital role in a business). At 12 dollars there will be a mass migration from the suburbs to the cities where they can rely on public transit more readily (suburbs are a creation of cheap fuel). At 18 dollars inner cities will become completely renovated to house more people and work more efficiently. Either you will live in the city, small compact towns or you will live in the country as a farm.
So as I am reading this book I wonder what position I will be in the future. Will I have to relocate to the city since I have chosen to be a nurse? Or will I manage to live in the rural setting some how and farm and nurse at the same time? I started to think that it would be okay to just have a big garden somewhere in the city and call it good—no horses. I told Amy that and she looked at me questioningly. “Are you sure you would want that just to save money on gas?” That got me thinking. Would I give up on my dream to farm with horses just to save a buck? Nobody likes to give up on dreams and especially for me. Following dreams is part of my identity. I had the dream of saving the world once. Went to Bolivia, Peru, and Ecuador trying to do useful humanitarian work. I had the dream to be a dog musher in Alaska. Went there. Lived on a Glacier. Even trained Iditarod sled dogs. After Alaska I had a new dream: farming with draft horses.
So as I thought about Amy’s question I realized I couldn’t give up on draft horses. They represent too much a part of me--my dreams.
I’ve also realized that they are not just my dreams. It has become just as much Amy’s dream as it is my own. She wants to live that dream. It has also become a part of her identity as well. As we water and weed our garden I catch her talking to the plants as if they were her babies. She apologizes to them for bad weather and for not watering them sooner.
If the future is as bleak as this author made it sound then we will have to sacrifice and be innovative but we'll hold onto and work towards our dreams no matter what.
