18y, looking for advice on how to position myself best for the long term.

For context, i position my portfolio as the following:
Core Holdings (30-35%)
- RSP, VXUS, VHT
High Conviction (45-55%)
- NVDA, MU, AMZN, LLY
Moonshots (10-15%)
- IBIT, RKLB, OUST

aside from IBIT, i use my “Moonshots” to swing trade, so i’ll eventually sell out of RKLB and OUST in the short/mid-term.

i’m worried that since i’m so young and my time horizon is so long, im putting too much into my Core Holdings, and it may be better to allocate more money toward my High Conviction and Moonshot positions. alongside contributions through work, i want to get to $100k by college graduation (22y), and $1M by 30y.
