Are there any other investments I can consider for girls my age? I'm a high-risk taker and am able to swallow losses quite well. Hoping to enjoy around 12% time-weighted return this year. Any advice?

21yo female. $38k cash in bank, $4k in Stashaway 22%(current return +12.23%), $2k in Syfe reit+ and own 400 shares of OCBC and 300 shares of DBS. Hospital and life insurance covered. No tuition loan. Bought most stocks and put money into robos at 3rd wk March when market was the lowest. Gaining a lot now. No intentions of marrying anytime in next 5 years so no consideration for housing or big items savings. Monthly income frm part-time tuition arnd $2k after lifestyle deductions.
