Releasing what no longer serves. People often say let it go, but it is easier said than done. Letting it go is a process that you need to constantly work on.
I have been through the process and I am still working on the process. The first thing to do when letting go is to make a decision that you want to let it go.
The second step is accept that you cannot change it. The third step is to do the work, this can be done through meditation, screaming in a pillow, exercising or whatever works best for you.
You will know you have let it go when you feel at peace when you think about it. Hope this video gives you some insight into the releasing what no longer serves you
