On expression You have many thoughts, feelings, and desires, and even a want to express many of these either through words or actions. Often, you want to tell others what you think or how you feel because you feel as though they need to know and that it will make a difference to tell them. Refrain. Usually the expression of your thoughts and feelings makes no difference and in fact makes you unnecessarily transparent to the point that you are no longer worth talking to. Don't be so quick to remove the veil of mystery from what you do and why you do it. This is not to say you should lie or deceive, but simply that you do not need to be outwardly expressive of every thought in your relations with others. It usually results in the downfall of many relationships, for a variety of reasons, but the underlying cause is that you have been far too expressive in what you think. Contrary to your belief that it makes you more transparent, I think it also makes you appear less sure of yourself because you are expressing all of the thoughts that are not yet fully developed. They are not worth expressing yet! Quiet yourself. Quiet your mind.
On heroism The heroism that you see portrayed in fiction of any sort is just that—fiction. Never forget that the world you live in does not call for you to be the main character. Life is not about beating the odds, being a hero, saving the day, or miraculous feats. These are all examples of narratives that others will create in their own heads (because they never get out of their own heads) and drive themselves insane. Narratives are purely fictional and have nothing to do with your existence as a human being. The one aspect of heroism that you should aspire to is helping others relentlessly. However, be careful not to associate being a hero with helping others. A hero who thinks of himself as one has forgotten the people that he puts on the mask for.
On justice It is not your job to bring everyone to justice or to right every wrong. You see, in countless examples both fiction and non-fiction, those who concern themselves with justice often find themselves in great trouble to bring it. Many not only fail to bring justice, but their actions result in numerous unintended consequences that never had to happen. When someone has done you wrong, learn to turn the other cheek. Do this by default rather than fighting. There is a time to fight and there is a time to defend yourself, but these should not be your default solution to any problem, verbal or physical. Bringing justice to another person by defeating them or taking them down will only put you in a ten percent better place than them where you must await their counterattack and defend yourself from future vengeance. Avoiding justice and going in an entirely different direction where you simply aim to do the right thing given your circumstance will keep you equanimous and allow you a clarity that will put you in a ten times better place than before. Be concerned with long-term success rather than the short-term high of having defeated another person or having brought justice to a situation.
