How People Becomes Lazy?

Last week I really want to write something on this page, but unfortunately I could'nt find out the right topic to blog. It was a lazy week for me. Not much work. Simply sitting in office from morning to evening, did'nt go for meeting customer. Browsing through pages was the only thing I was doing. How come I become so lazy? Is that being normal for me. I never wanted to be lazy. So being lazy is purely my decision. To an extent yes its my decision to be lazy. Or I being bored of doing the same work for the past two years. Or I being bored of the circumstances around. Might be yes for all those questions. I always believed that hardwork gives me results. And its being right for me. I always worked hard for my results. I worked for my targets by selecting the tough route instead of going for short cuts.
People tend to be lazy and bored when the circumstances around him take a U turn which become unfavourable for them, even I am in that situation. I always enjoyed doing each and every bit of my work. Even if its meeting new people, talking to existing relationships, product presentations, activities, team meetings, tele calling. I always compete with myself to enjoy it. At one point of life I just realized that every mood am having is created by myself, am the sole responsible person. But here am I boring myself and becoming lazy. Even am becoming lazy in making a blog. Still I beleive these situations I create myself. I am the person who got to pep my spirits and get back to old style of living.
