Giving up or letting go...

When should one give up? When is it acceptable, if ever?
In any circumstance, whether it be in a struggling relationship, the difficult pursuit of a dream, or whatever process we might be going through, we all come to a point when the thought of giving up knocks on our door. This tends to happen when we're tired, when we feel like there's no more strength to fight inside of us, when we're overwhelmed, when we've lost hope, that light at the end of the tunnel that kept us walking towards it, but all of the sudden is gone...or at least so it seems.
The reality is that giving up has been an option chosen by many, if not by all, at some point or another. There's a point during the journey, when we are so tired, drained and weak that we feel that the reason which got us there on the first place, the purpose for which we're fighting for, is suddenly not worth one more effort. But, does that mean that it really isn't? Could it be that the fight has gotten so intense and, since we're already tired, we'd much rather tell ourselves that there's nothing else to do? That's definitely possible. I mean, can we proudly say at that point that we've done all we can, given all we have, gone as far as we can, pushed as hard as we can and held on as strong as we can? Can we say that we've tried everything possible in our power? If the honest answer to any of these questions is no and we still choose to give up, there's a possibility we might one day face regret. However, if the honest answer to all these questions is yes, then we wouldn't be actually giving up, but instead, we would be letting go...having in our hearts the satisfaction of knowing that we did our part.
Whatever our circumstance, whatever our struggle, whatever battle we might find ourselves in today, let's make sure to fight with all we've got. Let's not see giving up as an option, but instead, let's remember that, as long as we're fighting, we have a chance to win.
