Welcome to the forum.
I have spread alot of advise through this forum and I produced a video series linked above. I also start a live stream for CAD and CAM , with the main purpose being to walkthrough Fusion issues that come up on the forum. I will also live stream my own work for customers as i am doing it so people get a feel for the work flow.
(I am about to start a live stream in 5-10 minutes 5:45am PST )
If you have a specific issue post a new topic and I’d been happy to walkthrough it with you.
The best advise I can give in start with very basic piece and build your foundational skills. The first vide on the series above is a simple plate , go through those steps several times before moving on.
