Veteran Investors, what was your investment strategy when you were younger?

I’m 24, have a decent paying job, and saving a lot of money. My investing philosophy was to buy and hold for 5+ years. But recently, I’ve been itching to say trade (not play options). But I wanted to get some advice pertaining to the title. Would it be smart to keep a portion of money for long term investments and have a little to play with? My ultimate goal is to build wealth for myself, but I’m not sure if I’m doing it right. Thanks
