Knowledge is power. Acceptance is freeing. No matter how much something hurts or how bad you feel about a certain person and/or situation, acceptance lets you make peace with yourself.
When you realise that there is absolutely nothing to be done, you stop waiting in vain. You shake off ghosts and shadows from the past, lay to rest the hope of breathing life into wholly dead ties. I’m not saying accept negativity or anything, I’m just saying acknowledge the truth and deal with it. Face it, absorb it, keep moving forward.
There are times to fight, to retreat, to hold on, and then, to just let go. The key is to know the difference and act accordingly. Make room for those willing, waiting, wanting to make room for you too.
