Oh but there are so many. I don't even know where to start. I suppose it is all a matter of scale.
I have sooooo many books that I've purchased but never read.
I have so many food items, I've never eaten and either sit in my cupboards taking up space or in my fridge until they are reduced to a puddle or the smell drives me to act.
I've got several outfits which I've bought without trying on and now hang in my closet with the price tags still on them. I keep meaning to alter them or donate them or lose weight but never do any of them.
I bought a pair of roller skates at the age of 20 that I thought I just could not live without. They were expensive considering I had NO money back then. I used them 4 times!
I got suckered into buying this homeopathic kit of pills which were supposed to make child birth more bearable. Do I have stupid tattooed on my forehead?
My greatest financial mistake was probably not cashing in or moving my 401(K) from my American employer when I moved permanently to the UK. I don't actively manage it and I know it has lost value over the last few years. Mental note to self: stop making this mistake and do something about it for heavens sake, regardless of the exchange rate and penalties!
