I am not an expert at all but you'd better register on some Blender specialised forums, and find a lot of time to study youtube tutorials. Starts with simple geometry, cubes etc, build tables, houses, common objects such glasses, bottles, then a bit more complex ones such stairs etc ... Virtually, all can be started with : a cube and a circle ! Including the most detailed airplane ! Then you need to develop some special techniques to build " properly " and saving as much polygon as possible. For me, the hardest thing in 3D modelling is making things as detailed and accurate as possible while aiming for lowest polys ( for its evident use in a flight simulator or any video games ) Check here : http://blenderartists.org/forum/%C2'> But if you ask questions such how to make a table, they will laugh at you so you'd better get used to Blender interface and basics first with all the great youtube video tutorials Hope it helps !
