This is my Long Term Plan. Are there any loopholes in it ? How can I better refine this ?

Just some back ground - I have a few grand in my savings account. Just been saving that up for emergencies (Rookie mistake I know, I am immediately going to put that into a HYSA).

My employer matches my 401K up to 6%. So I am currently contributing 8% of my paycheck to it. So total is 14% here.

I have been reading a lot on the web and also was in a Youtube rabbit hole. So my next plan forward is to open a Roth IRA and Maximize it for this financial year. Then I am going to use that money to buy VOO/VTI - basically ETFs.

I will also be having $500-$700 per month once my car is paid off in the neext few months. My plan again is to set up automatic purchases for whatever is available in my budget for that month again to buy ETFs (VOO/VTI).

I am not interested in the swells and dips of the everyday market. It gives me too much anxiety to constantly monitor entry points, exit points, tickers to buy etc

Are there any fallacies in my approach ?
Is there any other better way ?

Please let me know. My plan is long term financial stability.
Thank You in Advance :D
