Unusual Week

My energy has been unusually high this week. Some unusual things I did:

• Tried (and succeeded partly) to stay consciously relaxed throughout my day - be it at office or home.
• Walked from office to home on 4 days of the week (more than 3 kms distance). My legs did not ache a bit. On Friday, I became more walk-hungry and hence did a round each inside 2 nearby parks before going home. I was a bit baffled when I found myself enjoying the process !
• Got a caprice to try out an interesting idea that sprung in my head, at work in the morning. Finished implementing it on the same evening, which I had thought would take longer.
• Cracked a couple of data structure problems with unusual ease, thanks to the new fresher in our team.

Contrastingly, today(Saturday) was different, still unusual though.

• Got up in the morning and decided to do something serious that I had n't planned at all. Anxiety shot up.
• During the day, I was involved in something that kept me anxious.
• What I had always thought to be my strength - let me down totally.
• Used auto rickshaw and walked very little. Now, its time to go to bed, my legs are aching !

Do I see a pattern ? The first point in each of the above scenarios tells me something...
