There's a book by Tony Hsieh (Zappos founder) called Delivering Happiness.
Near the end, he talks about three types of "happiness."
The first is pleasure. It's from food, fun, or other external experiences. While it can bring temporary happiness, you will always be looking for the next fix.
The second is happiness from passion, such as a hobby or working at your startup. You can go for years without success and still feel happy. However eventually you'll need some type of progress to keep going.
The third type is happiness from purpose. Think of it as working towards something bigger than yourself. This type of happiness can last a lifetime, even if all you do is sacrifice for it.
