Im totally with you there, when i start more that one project I can feel a little overwhelmed, i do better work when the focus is on one project. If I get bored or frustrated, I'll do something other than modeling for a while so i dont burn myself out which leads to fewer mistakes.

Currently working on Revell 65 mustang 2+2 fastback, im not really a car guy, but every once in a while I like to try one. I have yet to build one that im satisfied with.
