"Life on life's term's" was a totally new and foreign concept to me when I first heard it here on SR.
I spent a lot of time considering this and I was able to make a huge leap in maturing when I realized that life is life is life and it applies to all of us. None of us are immune to the highs and lows, the tears and the joy.
I needed to grasp that I am not a delicate snowflake, that no one understands me, nobody knows the trouble I've seen, blah, blah, blah.
Good things, bad things and in-between things make up life and once I accepted that, I could move beyond resenting everyone and every event and stop feeling sorry for myself.
Accepting "life on life's term's" was absolutely liberating for me and is something I work on accepting everyday.
