I guess there both benefits and weakness for being either an introvert or extrovert. I know people who are able to switch from being an extro to into and vice versa and i guess that is the best. Being an intro helps in concentration and sometimes meditation but a big con is becoming timid and shy with time and this could breed laziness while being an extrovert makes you inquisitive and outspoken which is a good leadership quality you might also say the wrong thing if you are not careful sometimes and this could land you in troubles
