So, I was teaching my friend, who is new to investing, how to invest in M1 finance. As she is a PhD student with busy schedule, she wanted something relatively safe and with less hassle to manage. So, I naturally suggested $VOO (S&P 500 stock). Also, she didn't want to constantly check or have to manually deposit every month, I recommended her to use recurring deposit and auto-invest feature of M1. I send her a tutorial video.

And, as absent minded as I am, I turn on the auto-invest feature but forget to turn off the button. And, I buy around 10% of $VOO. 😂 Don't be like me, and add 10%+ position, double check you auto investing features.
