Aiming to achieve FIRE in 15-20 years, 70/30 split between VTI/QQQM?

Basically what the title says. I want to be more aggressive and tilt towards tech in my taxable bridge account (main investment account). I am investing in VT in my Roth and 401k, but want to be more aggressive by adding in QQQM and VTI (only US market).
