Are you living in captivity? Your obvious answer is clearly NO, but it is worth thinking about it once again. If you live in unforgiveness, if you are unable the wrongdoings of others towards you, then you are actually living in captivity. Did you know that? And the prison is the one you are living in, because you hold onto your anger towards the other person, the company, or whoever has done you wrong, and it makes you look back, instead of moving forward. If you want to be free, if you want to take action and move forward, then you need to learn to forgive, even when it is hard, and when it is tough.

Don't fight the battles of the past and don't be stuck in the past... it makes it impossible for you to move 100% forward. You can learn from the past, you can take action and change, but do not dwell on a past in a way that makes it impossible for you to move forward.
I believe there is lots of wisdom in today's quote from Hannah Arendt, don't you think so as well?
