Even a smart-aleck cannot be sarcastic or flippant all the time. This advice I read today is too good not to pass on; too good not to follow.
Don’t waste your time listening to false praise or distorted criticism. The praise will go straight to your head and the criticism will go directly to your heart. Both will lead you astray and both will damage the work God is doing in you and through you. --Pete Wilson, on his blog Without Wax.
