I think......

Besides my dirtbike, the Dart is the only real toy I have left.
The bike will go long before the Dart.

One thing I found out is that if I have any little thing on order for it that it keeps me exited about it.

Personally, I think you should keep at least one project, as it is too depressing to not have any toys at all.

Over the years I have lost a TON of things I really enjoyed to raising four kids, house payments, bills and stuff like that.
The Dart is my toy and I'm pretty damn selfish about it sometimes.

Keep at least one for your sanity.
