biggest tips I can give you are this.
Guide the piece of wood into/around the blade just think of it like holding and guiding a steering wheel of a vehicle, don't push it, let the saw work.
When doing a piece with inside cuts, drill the holes then flip the board over and take a counter sink bit and slightly drill each hole to form a depression in the wood. Saves hours and your back, the blade is easy to thread then.
Practice techniques of making sharp corners, they help immensely and I use different techniques in different scenarios.
Do 98% of your sanding prior to ever touching the piece of wood with your saw or drill (press)
Lastly when you get frustrated and you will when you challenge your scrolling skills, step away and go do something else for an hour, day or more. Then you will come back fresh.
Have fun, wood is awesome you can do anything with it
