The way to fight this is to do the opposite of what you want to do: When you’re unhappy, don’t curl up and watch a sad movie. Exercise, call a friend in need, and read up on happiness instead. You will be reprogrammed for action.
Once you’ve reflected (not ruminated), learned, taken action, and reaped the happy rewards, it’s time to make sure the benefits are not temporary—that you don’t fall back into simply wishing. The key is sharing your new knowledge with other people.
Like the law of action and reaction the more effort you put into anything worthwhile, the more successful and happy will be the results.
Good medicine.
