Life can be trying, but if you do not try, there is no life to speak of. When things gets better with the addition of your energy, enthusiasm and belief, then you've made a difference. Freedom is a metal attitude. Pressure is nothing more than letting your expectations exceed others expectations. Enthusiasm is nice for most things, but not for work, it will get you into trouble.
Enthusiasm makes some people feel uneasy.
Truth is a perception of one's own reality. Truth is a personal thing. Life is a marathon, not a sprint. Experiences were placed in the pathway of life for appreciation, if you stop and notice. Stop anyone in the hallway and tell them something nice.
