Hmm... A principle to always keep, no matter what the situation. That's a hard one. One that comes to mind is to always defend those you love, no matter what the cost. Do anything it takes to keep them safe. Never harm anyone if there isn't a reason to. But I feel like many people would consider that a principle to keep.
It's pretty difficult to think of one principle that one should always keep no matter what happens. But I do think that it's important to think about one's state of mind. I believe that it's important to move on from the bad things that happen to us in life and to let go of grudges, resentment, or what could have been. Should have, could have, would have. We should let go of those things. If we hold onto what happened in the past, then we can't face the future. We need to learn to forgive and move on, whether it's forgiving someone else who's wronged you or forgiving yourself. Yeah, it sounds really cliche and cheesy and whatnot, but I think it's true. No matter what happens, you always have to make sure to check your state of mind. Sometimes the internal part of you is more important than the external.
I believe that it's important to let go and move on from the mistakes and bad events of the past. It does no good to hold onto such things. In any situation, if you make sure that you aren't holding onto the bad things and focus on turning the problem into something good, you will have a clearer mind and feel better. That's another thing- being able to see the bright side of things. No matter what happens, if you hold onto hope and don't give up, then you can never count yourself out right away.
