Basics: I am a 27 year old overweight guy. About two years ago I lost about 60 pounds of weight by using this analogy that I have written below. I have, however, re-gained about half of this over the past 1.5 years, and I am starting again today.

Firstly, for all intents and purposes, let us assume that cars are sentient and are capable of growth and evolution (or the opposite).

I am one of those cars. I am a somewhat beat up 8 year old Škoda with a diesel engine. I have missed quite a few services and some of my parts are starting to wear out. Also, I am starting to resemble a mini-van from some angles.

I need time to warm up in the morning and my engine backfires often, because my owner usually fuels me with some low-grade limp-wristed cheap diesel that´s probably meant for a different climate.

I can go fast for a while if I am really being caned, but my engine tends to overheat and some body parts go to shit after a long run on high revs. I usually have to cool down for a while after something intense. Sometimes for days, even!

But I have a dream. I want to become something else. Something better. 

I want to become an Aston Martin Vanquish. I want to be fueled by the best fuel available so I can put out as many horsepower as needed. I want to wake up with a roar!

Now, I know that cars cannot change, no matter what fuel you put into it or how you treat it, but we can. I can.

I have a really beat up diesel, but I have a dream where I become a very cool car.

I need to become a Vanquish for a day or two, and is it possible to do this by just driving a nice car? If not, I need to find a way
