I have found at times we tend to get stuck in a certain way of thinking. We get focused on one or more negative thoughts that we for some reason we believe we can not let go of. If you focus on negative thoughts you leave no room or time for all the positive thoughts trying to break through. We allow outside influences to control or lead or way of thinking as well, mental and emotional discipline is something very few have at a high level and is something we all need and could use.
Many Eastern world philosophies and religions focus on centering the mind and controlling emotions. Methods such as meditation and physical arts such as Thai Chi and yoga also can help with mental/emotional discipline. To allow circumstances and external influence such as other people around us and their beliefs and opinions to control our mood and state of mind is basically surrendering all to chance and happenstance.
Humans have the unique ability to choose what they feel, think and do through their will, This is what makes humans one of the most unique species on the planet. When one learns to control their emotions and thoughts there is very little that person cannot do or face in life. Emotions such as fear, anger, jealousy, greed, and pride only hinder your true potential. They are the stumbling blocks of human existence and the enemy of our spiritual advancement.
Life is the greatest treasure we have and when we put material gain and self-gratification above our own life or that of others, we only lose sight of the things in life that truly matter. Take care of the material things but do not let the true treasures of life be put on the back burner.
Live life fully by your own will, treasure those things in life that truly matter to you and do not allow the opinions of others nor the trap of greed and envy stand in the way of your true happiness. Be the master of your mind and heart, live life as the master of your own destiny.
