Having the flu is no fun. The best thing to do is accept the fact that you will be sick for awhile and then patiently wait for the recovery period to set in. See it as a perfect opportunity to reflect back on your life and what you have or have not achieved and contemplate about nothing else in particular. Once you start feeling better resist the temptation to speed things along. Just let it happen. When you feel like you can go back and work again wait a couple extra days. You will be glad, feel much better and will have learned much more than you would have ever expected from having the flu. See, even the most negative events can be turned around to reveal more positive tendencies.
