Yet I do it for a living, because building things is incredibly satisfying. Ya about 90% of the time I'm kind of bored, but actually finishing things (useful things!) makes it all worth it.
Interestingly I found that I have the same feeling in other endeavors. When I remodeled my house I found construction to be just incredibly dull. But man, the result was absolutely worth it. I don't know if I've ever felt more satisfied with anything.
