Just go into the garage/shed, pick one and finish it. Use bits from the others if you have to. Then and only then pick another and move on.
Then you'll get the a point than you throw any bits you have left on a frame you have left and probably decide this is your fave bike and ride it most.
As the weather is so bad this weekend I'm going to take your advice and finally finish the build I've been working on for the last 2 years! All I have to do is re-build the rear wheel and apply frame decals. Thanks Gil_M. Get well soon!
