Yes, as a starter, do not use the bevel modifier and also try to never apply it. If you can’t guarantee for a clean topology, it will mess it and you don’t get it cleaned. Use it after everything is completed and give it more control with edges marked (Bevel weight). Remember that a Subdivision and Bevel modifier love quads, otherwise custom topology is created without your control.
Start with a flat plane and use the “Orthographic View” (Numad 5) with the appropriate front (Numpad 1), side (Numpad 3) or top (Numpad 7). Remember you can use the solidify and mirror modifier and just need to work one side. Blender will make sure anything you do will happen exactly on the other side. Do not apply modifiers if you don’t have to.
It will take some time to learn proper topology flows, so don’t let you get down and try more. It’s a good advice to stay co-planar on your transformations as long as you can.
