There have been threads like this, but they're old (like, a year back, I think) so I think you're okay here.
Can I choose all three, seriously?
Courage - I consider this my "Triforce-affinity," but I don't know that I have enough. I mean, I'm a hero on the Internet. I am very brave when speaking my mind online - I have been known to let fly with my opinions on things in hostile environments. (For example, standing up for the validity of video games as an entertainment/artform against a horde of elitists who sterotype everyone who plays them as being unable to read. I game. I also *write* novels for fun)! I have a bit of an adventersome spirit when exploring nature, to the point that loved ones have worried about me when I go out on walks because I don't really heed natural dangers... At the same time, there are things I am scared of and just won't do: You can never ask me to parachute or bungee-jump, EVER. I can't walk on ice. And, in every day life? I lack a certain self-confidence - I feel like I'm "unable to do anything right/adequately" so I basically have to grit up my courage to do *anything* special, so, yeah, I could definitely use more of it.
Wisdom - I think *everyone* can use more wisdom. I've been told I'm wise by some people, but, honestly, I wonder if my wisdom is the wisdom of fools. You see, I see wisdom as a spiritual quality - it's not just intelligence. That alone puts me at odds with many, many people (who think that anything "spiritual" is stupidity). I think the problem with wisdom is that you never know when you really have it, because one seeks it to find answers, but it's said that the truly wise end up with more questions than answers. I feel like I have more questions than answers to life - and I'd really like to *know* more.
Power - I'm pretty darn powerless. I don't have enough courage to take hold of it when it comes my way, it seems (see Courage). I try to use what little I have for good, but am aware that if I were to ever gain a great amount, there will be a huge temptation to use it for selfish ends. It seems like neither of the other two qualites are any good without the power to use them. When I see suffering and know I don't have the power to stop it or ease it, I feel bad. If I had power, I fear I'd forget about the suffering of others. Power would be a great thing to have so long as I remember how to use it - in other words, it needs to be balanced by Wisdom and Courage.
You see, they all balance each other out, so ideally, I'd like all three.
