Hello and welcome!
First two suggestions:
Start a new thread. "piggybacking" an old topic often isn't a good path to getting answers.
Ask more specific questions. This seems very broad. Years of details to be discovered.
There's a lot of material here. tutorials, tips. vast amounts of info spanning years.
Tip one. Read the user guide. Good start. Many people don't.
Tip two, watch the assorted video tutorials from all versions. There's a lot of material to cover.
Tip three, start working through the tips and tricks threads. Even more stuff there.
And feel free to ask questions here in the forum. Lots of helpful folks eager to answer.
