One item in particular seems worth the share:
3D World: Could you share a technical secret on how you work?
Lose the undo key. Tweaking should be reserved for when you have finished the stage of the project you are working on, an extrude should take 1 second, not 10 minutes.
Try to work in passes, start by blocking, then refine the whole thing, refine it again and repeat until you are happy.
If you create amazing landing gear on a blocked out plane, when your supervisor comes he will see a blocked out plane that took hours to make. I say this because we never finish a project to perfection, it is simply taken away from us because of time.
I guess I’ll stop my unfortunate habit of modelling photorealistic nose hairs on otherwise undefined blocks immediately.
