Not the best thing to do . I think it ' s better to explain it on any other day , as birthdays are highly important at this age . I remember myself waiting for every birthday and my parents were planning the gift accordingly to what I were into . Not to mention that he will be overexcited for the fact that it ' s his birthday and hyped for the presents more than for adult things . Life is rough and honestly shit compared to the amusement and fun of being 14 years old . Your son will do a lot of research on taxes , savings and other adult stuff , time flies . But I think the better way to do it is to combine the savings lesson with investment and entrepreneurship lessons , explain the meaning of innovations and technologies in various businessesetc . Money loses its value , but minds not . So in my opinion leave it for some time . Probably talk about it when he will be in mood or at the evening of his birthday .
