buzzing around the ears

What do you do when some things you hear feels as irritating as mozzies buzzing behnd your ears when you are in deep sleep?

There is a chinese saying which I always bear in mind:
涼葯苦口利与病

忠言逆耳利与行

it means that when you take bitter medication, its beneficial for your illness, (most chinese herbals do not appeal to the palate)
Like wise, when someone is giving genuine advice beneficial to your behaviour, it is usually unpleasant sounding to the ears.

I have no problems pointing this saying out when I'm trying to tell someone that its good for their health to take bitter medication, but when it comes to my turn to take the bitter medication, I ask myself WHY ME? ha ha ha

Do you encounter situations when someone is telling you that some of your actions are not appropriate? What are your responses to them? Do you take a min to listen carefully to what they have to say without feeling defensive about your own behaviour?

Its only true friends who care about you who would tell you off when you misbehave, treasure them.
