Use Solidworks built in tutorials click help and then Solidworks tutorials and they have basic ones available. Get more advance buy a book.
And when you run out of tutorials built into solidworks you can register on their website. Find the training files. Many parts already built in various areas of expertise, advanced modeling, weldments, sheet metal , ect. Take their built part make a drawing from it then create a new model from that drawing. Then you also have the sample part for a reference. Use the rollback bar to view each operation step by step because yes beginners tend to make models a lot harder then they need to be. Match the materials between both parts and check their mass. If you made your drawing and model correctly the mass's will match! Happy modeling.
