One does not enjoy meaningless talks now. He is more interested in serious and intellectual talks and debates. One tries to make things simpler and do them one by one. One gets the ability to be more sarcastic and negative in speech. Sense of humor also tends to be more towards disrespecting others. One does not entertain people like he used to do earlier and may be labeled as too much withdrawn. The focus is more sharpened which makes you not spare much time for others.
