...bravo to Samuel Clemens, still able to catch the public’s attention a century after he expired. He speaks from the grave, he writes, so that he can speak freely — “as frank and free and unembarrassed as a love letter” — but there’s precious little frankness and freedom here and plenty of proof that Mark Twain, in the hands of academics, can be just as tedious as anybody else when he is under the burden of his own reputation. Here, sandwiched between a 58-page barrage of an introduction and 180 pages of footnotes, is a ragbag of scraps, some of interest, most of them not: travel notes, the dictated reminiscences of an old man in a dithery voice...
There's a big difference between working to put food on the table vs.working for the "extras" such as summer camp or a vacation. Both are legitimate but it's essential to be honest about your motivation. Knowing what drives you will help you keep your priorities in order. When my children were young, I worked for the extras. However, instead of stopping when I earned enough to help with vacation costs I kept right on going, becoming a workaholic in the process. It didn't serve me or my family. When I recognized my error, I was able to cut back on work in order to create a healthier balance. Now that my children are school-age and I'm working to help cover orthodontia, tuition and retirement, I've increased my hours accordingly.

When you know why you are working, it gets easier to decide what kind of boundaries you'll adhere to.
