Miserable failure

This stemmed from a talk that I had with someone so; below is what I'd said: if you want to fail, at least fail trying to achieve something that you wanted to achieve that way in hindsight you can always tell yourself that you did your best. So, what's a miserable failure? if you fail trying to achieve what you never wanted anyway, you just end up spending your energy, your times and emotions on something which really doesn't matter and the more you get involved, the more you get sucked in...going by this definition at least I can't call myself a miserable failure; a failure, yes but not one of the miserable kind.
