you’ll be amazed at your balance if you consistently do this weekly for one year.
it seems like OP plans to do it every month. and the value will not be too surprising.
but seeing the enthusiasm of OP who wants to invest at a young age, that's very good. he can start from a small amount, but when he has a job and can allocate more, he will increase his investment in the future.
the most important thing for OP is to do it consistently. don't rush with large ownership. he must adjust his mentality to be strong with what happens in the market. because the bigger the investment ownership, the greater the pressure he will get. starting small, will start to train his thinking to be stronger with the understanding he experiences in the market.
