Train out Impulsiveness?

Impulsiveness is a trait of the natural life, and our Lord always ignores it, because it hinders the development of the life of a disciple. Watch how the Spirit of God gives a sense of restraint to impulsiveness, suddenly bringing us a feeling of self-conscious foolishness, which makes us instantly want to vindicate ourselves. Impulsiveness is all right in a child, but is disastrous in a man or woman—an impulsive adult is always a spoiled person. Impulsiveness needs to be trained into intuition through discipline.

Oswald Chambers

Just thought I'd put this up. I wonder how we can go about training impulsiveness out of ourselves? By we I mean me of course, but, you can all join in too.
