I was looking back at old journal entries recently, and instead of embarrassment I went into them seeking a connection with my younger self. While lots of my entries were filled with minutiae, those minutiae were incredibly important to me at the time. I chose not to dismiss or belittle them, but give them the respect they demanded. I wrote them, so there was some importance there.
In other words, I was practicing being compassionate with myself. It's easy to do this with things that are in the past, for me, but it is also limiting as the past can't be changed. So I'm working on being compassionate with myself in the now.
And sometimes, that is what I need the most.
