I just purchased a house that has a garage completely empty...not a
shelf or bench in site...(unlike my last home)...Im headed for some
woodworking...my main project will be putting some shelves up....the
garage is completely drywall..so Im curious how to attach the wooden
2x4's to the drywall so the shevles will be secure and
steady?....thanks from a new woodworker in training.

Um, same way you do INSIDE. To studs.

But consider cabinetry as your first project.
