I've tried taking this attitude in the past, but it only works if you have a well developed social circle with friends and colleagues who have a good estimate of what you think is important. Otherwise, you suffer from two disadvantages from the philosophy...
1) Information that gets to you will be filtered by an "importance guesstimate." Some information will not reach you, because your social circle will regard the info as useless, irrelevant, or "impolite." This last one is dangerous, because such information is the kind this disproves the axiom "What you don't know can't hurt you."
2) People in your social circle may have a higher view of their own judgment that they do of yours, even if they correctly know what's important to you. Therefore, you will sometimes get information you DON'T want and waste your time because your friends and associates will have their own agendas to push in providing extra info to you.
