Stop using your type as an excuse.
Yeah, you may be an XXXX. And that type influences your natural preferences. You may not like to speak in public because you're an INTP. You may not prefer to sit at home and watch CNN because you're an ESFP. Whatever.
But, dammit, your type does not dictate what you are and are not capable of.
Push your boundaries. And stop using your type as an excuse to sit at home/not get the girl/stay unemployed/act like a jerk/whatever the case may be.
