I think it's wise to understand the situation but not to close the envelope, so to speak. Don't shut yourself or entirely otherwise you'll become ignorant to the necessary day to day knowledge. But you definitely don't want to drown yourself in it. Everything is good in moderation and that's all you need to do is moderate. So don't feel selfish because you don't want to hear the bad anymore, feel relieved that you don't need to hear such large quantities of information and keep up with it all. Everybody has a limit and yours has been reached so enjoy your load off. You deserve one!!!!
