Big dreams

I just turned down what could have been an amazing business opportunity. I would have made almost triple what I am currently making and I would have been my own boss, working when I wanted and still able to keep my current job. So why in the world would I turn something like that down?
Well, the first reason may seem silly. I used to work for a company selling high quality knives. Just like the job I just turned down, I would be my own boss, visiting people in their homes and getting more appointments through word of mouth. Also, I would be making commission and would have my first few appointments with friends and family. I tried selling knives for about two weeks. I did not enjoy it. I despised it. So doesn't it make sense that since these two companies are so alike, because I didn't like the first one, why would I like this most recent one?
My second reason is probably more sensible. I have this dream of joining some organization where I can travel the world and help people/animals. Basically, the Peace Corp. Or an organization that is similar. I first had the idea of doing this last July. I had just gone through a difficult break up and wanted to do something with my life. However, I was quickly distracted by someone and the thought of traveling was gone. Until now. And I don't want this dream to leave me again because I get distracted by something. Whether it be another man or a job opportunity. I am refusing to become distracted and postpone my dream again.
Whether you agree with me or not, that is why. And I am extremely glad that I turned down the business opportunity. It may have been perfect for me and I may have enjoyed it and made millions. But in six or nine months, would I still want to leave the country, and ultimately leave that job? I would be distracted by all the money being made and that just cannot happen.
