"Things seem so simple when you are younger" we challenge close to nothing, take all principles of human interaction as a given and if we don't accept their enforcement we just get sad or experience agitation that is usually described by "they are mean" or " they are stupid" or "I don't like them".

Then suddenly for your 18th, 19th, 20th Birthday you are hit with a marvelous present: here's a brain, now it can generate weird thoughts, make you feel like nothing around you is real, has any meaning and neither do you or any of your petty efforts. Now this brain will work in this direction, regardless of your own personal desires, in fact it will encourage all of your mood swings, panic attacks and cowardice, as well as narcissism and hatred. 

Nonetheless, it also makes you analyse and process the information you are getting, instead of merely accepting it or going along with it. That way we get the great opportunity to become self-aware and work on our impulses. Finding the causation of an emotional reaction is to me very satisfying, like solving a little puzzle, at times it distracted me from acting upon my impulse now, the knowledge, that I will in a few minutes find the true reason for my reaction, which in turn will amount to my self-indulgence or the very apparent human self-centeredness, makes me reconsider my decisions and avoid public confrontation. I've lately decided that the said selfishness of most humans in a lot of daily situations, our self-absorbed anger at the rest of the species for not being smarter, is so ridiculous and counter-productive, that it gives me more discomfort to act upon it, than putting it out quietly and peacefully within myself, which coming from one overly self-absorbed human with anger management issues, is no pieceacake.

In conclusion, let me propose a theory for my future self:
As I know (as of recently) I do not like to be kind to myself very much. So I've had a brief moment that generated an progression of some memories and as it seems most of my life after 1st grade is in a tedious, not-fully-enjoyable cover. Speaking from my current perspective, I can relate that to stress and my constant strain for enjoyment and pleasure. Based on that, I deduced that my brightest, most memorable summer, is such due to the lack of stress and my allowance for reward.
