Life beats us up, yes, but it’s important not to let it make us bitter (or at least, keep us that way).
If life is rough, and you turn into a weak broken pussy about it, then yes, you have lost.
However, if you instead respond to life’s occasional harshness by becoming super calloused, mean, and staying that way, then I believe you have also lost, in a different way. Because either way, you still allowed things to change you, dramatically, for the worse.
I think it’s important to fortify inner strength, to be able to withstand life’s hardships; but it’s also super important to make sure you don’t make yourself so hard, that you turn cold. I think it is essential to be diligent in keeping a balance, to develop a way to process things that doesn’t steal away your shine, your joy, your lightness of being.
Life is already short enough as it is, & we will all be gone someday sooner than we think; there is no point in losing yourself along the way. Keep your heart warm.
