Win and lose
One of the things I wrestle with in my spiritual practice is the idea that you will never be able to truly win and truly fail — all mistakes, weaknesses and missed opportunities do not matter, unless you want them to matter (no point in doing so). More importantly, the positive things you do don’t matter as well. Leaning on them is sends you back to square one.
There is something spiritual about this principle itself, it somehow defines spirituality.
