Changing your personality
For a long time, within psychology, the consensus has been that personality is hardly malleable from a a certain age on (which is supposed to be around 17 years old). This assumption was largely based on findings, in longitudinal studies, that peoples scores on personality questionnaire dimensions are generally rather stable. In other words, it seems that many people describe their personality in a rather stable manner throughout their lives. But does this justify the conclusion that personality is not very malleable? I don't think it does. That many people do not appear to change their personality a lot during their adult life does not prove that it is not possible to do so, at most it suggests that it does not appear to happen too frequently.
