Where is the energy gone?

Today I completed my senior management training program of Engineers India Limited. It was a good program and the program was held at Surajkund, Haryana. I was surprised by the huge size of the property in Surajkund. Its so close to Delhi and such a nice property but I could not find out many people in the hotel. Their is a good swimming pool at the center. First day I had sometime to spend around the swimming pool. I thought I could speak to myself. But lo there were few week end couples and I got a new profession. They asked me to take photographs and once I started the process, then found that every couple ran to me. They were so engrossed in their life and talk that they could not guess that they are perturbing to someone else life.
I had to handle a bundle of difficult managers who were predominantly engineers and had no idea of management and were thinking that I was talking out of the box. Interestingly, when I started heating them and liking thier bad performance then there was pin drop silence. I hardly do such kind of stuff with trainees, but this time I had to. I remember I had done this with IPS officers while training them.
Why I am writing this stuff on my personal blog. Actually I wanted to write that I am getting tired these days faster than before.Earlier I could manage a five day training program alone, but now it seems difficult. I dont why is this happenning? Is this because I am getting older and over working myself. It may be there is something unknown happenning to me and I will only know about this at the last stage of life.

I got few interesting phone calls in last few days. Out of these calls, there was a call from Manaswini from London. She is travelling back home and called me from there. Though professionally she is doing fine, she was worried about her career and she was woriied about what she has not got in life than what she has already obtained on life. I dont know what to councel her because my philosophy of life is different than hers.
