Argh. I'm close to level 50 with VERY LITTLE progress made in the main storylines. Anybody else in this trap?
I've got a nice money making machine made in sanctuary and have the investor perk. So, I start the day by selling product and getting about 10,000 caps. Preston will usually cross my path and send me on a mission. I run out, finish the mission, come back, drop off my junk, and it's evening, so I sleep, and repeat!
Or I finally scramble out to try to make some progress, but I'll come by a firefight, grab the spoils, and have to go back to drop off. And it's evening...
Or I find a new settlement. Then I'll have to establish with vendors, blow my cap stash and crafting materials... So I head back to Sanctuary.
It's my OCD. I can't NOT do this stuff! I'm not complaining. I'm having fun. This game will last me ages.

Come to think of it. I spent 75% of my time in WoW in the auction house making money.
