21yo Portfolio advice

Hi guys, I’m a 21yo university student who is very interested in investing and the stock market. I try be as frugal as possible, have no real desire for material things and plan on having 90% of my wealth in stocks longer term (Warren Buffet is my idol lol). I’m sitting on a considerable portion of cash (relative to my stock positions). Considering my age and stage and that my investing time horizon will hopefully be for many years (50 years say). Does anyone have any recommendations or advice? Or things they wished they had done differently at my age, would be greatly appreciated :)

Note: The reason for holding cash is partly because I haven’t found enough sensibly priced businesses I like.
