What am I missing here?

In the last few months, I've been so busy in life, inspite of the fact that I didn't have a job. Usually, my life is such that weekends are so unplanned, but still those 2 days have always been hectic. Similarly, these past few days when I didn't have a defined 'day schedule', I kept myself so busy with Isha activities, cooking and friends. I can't believe I spent these few months without a television, browsing & blogging, books (that's a great surprise) and friendly calls.
The kind of activities I was involved in are so different from what I've ever done in my life. Procrastination was something that got out of my dictionary. There was no activity that I refused to do and no person that I refused to meet/talk to. I woke up everyday with so much energy and went about taking care of my To Do list. So much to do, but still not a moment was tiring. How can this be?
When some of my friends asked about missing blog updates, I realized that I was feeling so empty within and didn't have anything to blog. I don't remember ever feeling this empty.

Now that I've started working in a corporation again, life seems so different(and there comes the need to blog). It's a struggle to keep myself bubbling with energy throughout the day. What am I missing here?
