Need advice from only 18 or 18+ people!

I am 18 year old college student, earning a little side by side with studies. I started investing and it is going great.

I want to upgrade my horizon and as a kid who loved watching content creator on youtube, I am eligible to buy some of the stuff I dreamed of like

  1. DJI Action Camera
  2. Gimbal for my mirrorless camera
  3. Laptop

I want to buy all of this stuff from my earning and yes all of these things will somehow help me in upgrading my work but I am investing 60-70% of my earning in investments.

My main question is, "should I invest in myself for this year and then invest in mutual funds/stocks or what can be a possible solution?"

Need your help folks!
