Sometimes knowing and seeing things that others do not, or seem not to notice, like how people treat each other, or people you may have admired but know some dark secrets of theirs, can frustrate and make us angry. It is a battle to get through the struggle of life, especially if you feel hateful towards the very notion of living! I am speaking from experience, and the thing that helps me bear that burden, is to allow myself to accept and forgive the inadequacies of humans. Everyone is wrapped up in their own worlds, that is only natural since they are within their own minds and can only with a desire to learn, think about what other people are thinking or feeling. You and I are both guilty of this and although it seems unfair and injust, it is only human. Dissatisfaction with your present circumstances, also is very human! If we were to really be content, then there would be little reason for us to progress. I know its a cliche but the struggle towards an achievement is more important, to at least the individual, than the achievement itself. Dissatisfaction usually means that we desire something in our lives that is not present, it is the response that we give when we need to accomplish something. The fact is that reality really is whatever we percieve it to be and we can spend just as much energy expecting dissapointment as we can expecting success. Success will always bring new dissapointments and thus the laws of motion will eliminate any lasting contentment. Realizing how similiar we are to each other can temper our inclination to judge another for expressing traits in which we all posess. If you can describe yourself as being once a Happy-go-lucky individual, the chances are that, that person is still there, but has just gotten a bit jaded by the experiences of the past. Possibly that side of you was more accessible then because at that time you didn't know as much as you do now. The balance of wisdom opposed to cynicsm is a tough scale to carry, in your heart you know how to bring harmony to these conflicts, it is sometimes necessary to remind ourselves that we are responsible for maintaining that balance.
Take care of yourself and don't fall in the trap of taking things like this out on other people, even if only in your mind, the truth is that even if it is the smallest gesture of goodwill, it is the gesture itself that counts and it affects so much more than what you or I may think it affects. The knowledge of what each gesture of goodwill actually contributes to the scope of human kind is kept hidden from us, it is that limited understanding that inhibits the majority of us from actively displaying those gestures. Wisdom will allow us to accept these things, where as cynicsm will cause us to seek someone or something to blame. It is the test of the soul to grow wise and with wisdom comes warmth, it is the how we respond to the failures of this test, that determine wheteher or not we grow wiser because of it or not, it is the latter that chills us inside and brings to us desolation and cold.
Take care of yourself and know this, your success and potential is Crucial to us all!
