Here, Here brother. Well thought out and articulated.
Sage advise all of it and I would caution new builders to heed it wisely. I myself start many projects only to return them to the box for an unknown length of time.
The trick is to know when it's time to open it back up with perhaps fresh eyes.
The basics are just that, BASICS. Get them down first before you explore the world of whatever it is that tweaks you. Like customs? Go ahead and chop a top, but have a box stock build going as well [You're a modeler, having 2 going is childs play for us]. Switch between them as you hone your chops on the goal you have set for yourself.
There are many "Basics" builder tutorials within this site. Do a search and be amazed at what you'll find.
I'm amazed every time I do.
