I just started my first job and I have a RSP. I am interested in investing in other stuff however I am only going to turn 21 in a few months. Should I wait until I'm 21 to open a brokerage account? ?

No hurry, but from a longterm perspective start as early as you can.

here are some topics, I feel, to be important, particularly on what not to do.

but also forget the tech investing part in that text.

possibly - as to equity investing - You'll need only a single global

passive stock ETF (like VT or ACWI).

For Singapore residents: POEMS, FSMOne or Standard Chartered are all o.k.
