Investment Strategies for New Investors

Peace!
There’s so much information here and elsewhere on different investment categories. Everyone seems to be an experienced investor. It’s difficult to know where to start. I’m 63, married, working class and I’d love to access investment information for new investors with small amounts to invest example $100-400 per month. I’d like to be slightly aggressive so I can see results in 6 months to a year. I’ve been investing some crypto, some stocks, but still not sure what to do with my money to maximize returns.

Please let me know where I can access content and training related to my particular circumstance.
Thanks
