How can I maximize?

Already chipping away at my mortgage with extra monthly and yearly payments (locked into a low rate on a 30-year). Carrying no other debt, gamifying credit cards, tripling 401(k) match and maxing out my Roth IRA. Liquid savings in a HYSA, leftover money in an index growth fund, short-term CDs and Treasurys. Working a full-time career (40 hours) and supplementing that with a part-time job (25 hours), two freelance writer/editor gigs (5 hours), and a side hustle (9 hours). What else can I do? What am I missing? I'm talking about anything that can produce another $100/week in fewer than 10 hours.
