I'm 17m feeling like I'm so far away from 100k, I want to hit 100k by the time I'm 21 I barely started investing back in February of this year. I have most of my money in ETF's like FTEC, VXUS and VTI but I want to play around with some of the money and checks I have coming soon. I have about 6-8k in checks on the way and don't know if I should buy even more heavier on my ETF positions or try and mess with individual stocks to see how I can do. Any Advice is appreciated.
