Why are you focusing on cash for happiness? That is what each of these scream, money, money, money and more money. Do what you love, what makes you happy, what makes you feel like a child again. THEN the money will naturally come by way of your passion showing through your work.
Example:
I use to be a big wig suit and tie guy, was offered regional rep. over Va for a national multi million dollar company. Instead, I turned it down and quit, I wasn't happy.
I then got a job as a car detailer (yea, of all things), then a year later I opened my own small shop. It closed and I opened another, this went on a few times, all learning. When I started this I told myself I would be happy with $15 per hour ($20 today) as I just enjoyed working on the cars and talking to people who had the same passion. Plus was stress free, no meetings, no one barking at me, wanting to sue me for malpractice, etc.
Today, 10 yrs later, I am one of the top experts in my field, way past "detailer", but today I am what is known as a Automotive Cosmetics & Paint expert. I have trained body shops on how to paint, I aid local body shop supply stores when they have an issue, I do cosmetic paint repairs on high lines cars (Ferrari, Porsche, Lexus, etc).
Since I went after what I liked and I showed my passion, it paid off. Not only being on the top, but that $15 an hour I had hoped for.... turned into an average of $75 per hour. Like to see any corporate suit and tie job offer a stress free life, a life I set at my own pace and time frame and make what I make.
I ran after money with my first career.... you see where I ended up. Go to school, work for 7 yrs and you will ask yourself what I asked.... " why am I here? I am not happy ". Start off by doing what makes you happy, you will save that life change later on that many of us go through.
