I have sewn all my life and taught myself originally from the instruction sheets inside commercial patterns. If you follow those you won't go far wrong.
Go to your local sewing store. The staff will be delighted to help and tell you which patterns are easiest: Id start with "Simplicity" tbh.
Many years later, I found this book 👇 in a 2nd hand book shop. It's THE most comprehensive and clearly written handbook I've ever EVER seen.
Just checked on ebay. It's still out there.
