This may be obvious, at least if you have read Daniel Gilbert

In 2002, Jane Ebert and I discovered that people are generally happier with decisions when they can’t undo them. When subjects in our experiments were able to undo their decisions they tended to consider both the positive and negative features of the decisions they had made, but when they couldn’t undo their decisions they tended to concentrate on the good features and ignore the bad.

When reading my own writings a second time, I always discover typing errors, crude sentences, and other poor habits – blogs as snapshots of less happier minds?
