I’m just starting to invest and i’m 17 so far i’ve put into $ASO $SONY and $COST

i just want to know if this is a good start and should i put more into these? is there one that i should get rid of? also i’ve been hearing about $VTI and $VOO should i get in? is there any suggestions on what i should get into im patient so i won’t have any problem waiting on growth
