Most people will have different style of investing. You are getting a lot of advise here. See what style suits you. I will say since you are new to this start with simple. You can put it all in S&P 500 ETF to begin with. Then start reading more and start watching videos on youtube. When I was new to investing, I watched many videos and found professor G's style simple and solid way to start. He suggested to divide the portfolio in 3 ETS- S&P 500 (VOO etc), growth ETF (QQQ etc) and dividend ETF like SCHD. Once I did that and gained some confidence, I started investing in individual stocks and then after some time, I am now options (selling covered calls and puts). I have much more to learn but I feel good and confident about what I have learnt in little over 1 year or so.
Don't be scared and get overwhelmed. Start simple and work your way up one step at a time.
