20M Looking to see if anything is wrong with my approach

20M in university paying for everything started investing as soon as I turned of age. Maxed out TFSA, FHSA, RRSP, and the rest in non-registered. Work alot in tech and have a few side hustles, I just want to see if anyone has any advice on my investing approach and if I should be doing anything different. Basically dump in VFV and hold (diversify with TLT a bit) as I'm young...
