One of the most important life philosophies is to forgive and to forget. I often do not abide by this philosophy and instead choose to hold grudges. This is stressful for me because I constantly want to tell people why I hold such and such a grudge. Sometimes, the grudges are because of my own biases, and I find ways to skew stories so that my audience would be more likely to agree with me and why I am holding a grudge.
I think what happens mainly is that I lose track of the big picture and start digging deeper and deeper into the little things. I need to better learn to be able to step back, take a deep breath, and tell myself that every thing is going to be a-okay. And then to believe it.
