[Closed] Those impulse purchases

Following on from my whats it worth post, how many other people dive head long into the latest idea without thinking it through?

My latest was a result of watching too many videos and looking at too many build threads of dirt jump bikes on pinkbike. This triggered some childhood/teenage memory's from some of my best years riding with mates. So. Obviously the right thing to do was to build a bike that I would have sawn my arm of to have when I was 14. But im not 14. None of my mates ride Dirt jumps anymore... and quite honestly, neither will I! Problem is, I only really thought of this when it was too late and I had spent to much, I was committed to finish it. This wasnt even one of those 'i have to have it moments', I spent weeks planning and then further weeks buying the stuff in component form because it was easier to get it through the door than a whole new bike. Easier to seek forgiveness than permission? But thats another story. So it was a well thought out, calculated impulse with so many opportunity's to realise it was a daft idea.

Anyway it looks bloody awesome! But I know I will never ride it. Oh, and the latest impulse is to give BMX racing a bash but my marriage will not survive another bike appearing if I dont get rid of one. As hard as I try, she just doesnt understand N+1.

So who else gets themselves in these stupid situations?
