Diversification in my Portfolio

Hi everyone!

I’m 22 years old and have been diving deeper into investing over the past 5-6 months. My current portfolio includes COIN, TSLA, PLTR, VOO, SCHD, and QQQ. I realize it’s very tech-heavy, which is why I’m reaching out for advice.

I’m looking to diversify my portfolio and add more balance. What do you suggest I invest in to achieve greater diversification? My goal is to build a well-rounded portfolio for long-term growth.

Thanks in advance for your insights!
