Thoughts on my plan?

Brand new investor who wants to start and build long term wealth. I’m 21 and am trying to learn what I can. Opened a HYSA, and looking at ETFs and trying to learn more day by day. I have made a plan and would like to know how solid and likely of a good return it is, safety, etc. What else would you invest in or advice to me? What do I need to learn?

For Now I plan to:

General Webull Split:
80 VT, 10 AVUV 10 AVDV

In future?:

Roth IRA Split
• 32% NTSX
• 15% NTSI
• 15% AVUV
• 10% AVDV/AVES
• 15% DBMF
• 6% GLDM
• 7% EDV
