Time-off? Sabbatical? Break?

I have been wanting to take a complete break from work. Its been 10 long years of loyal service to the same firm and I feel I just need some time-off. So, I've applied for a 3-month leave without pay starting November and I'm really keeping my fingers and hoping it will come through. The thing is that my job is comfortable....to the point of it having become a little uncomfortable. Too much lethargy but with a fair amount of stress. I know what you're thinking...lethargy and stress? How can they go hand in hand. Well there are times when I feel extremely lethargic cos the work is so predictable. I know exactly how I am going to spend my time in the office. I could perhaps do a lot more if I put my mind to it.....but feel I dont have the energy or the motivation. And then there are days of complete stress, but also not the kind of stress which will make you do stuff more efficiently. I just want to have some completely stress-free time, discover the real me. I have reached a senior position and dont see where I am going.

And ofcourse I want to see how it would be to spend 3 whole months with my kids.

Anyway, I've been planning a bunch of things in my head. But things dont always (or rather they hardly ever) work out as planned and I dont want my time-off to be another stressful thing...so I'm trying to keep my mind open and be flexible about all my plans. But here are some things I would love to do during my break, in no particular order:

1. Take Karan for swimming lessons.

2. Complete my book (I have started writing a book on law but haven't gone beyond the first chapter).

3. Visit Ro, Beks and Aditi.

4. Take Kavya for some class in Vanilla.

5. Get Kavya to be friends with her Ammacha.

6. Lose 10-15 kgs.

7. Clean up my house from top to bottom.

8. Cook(or atleast find some recipes and teach my cook) to make tasty yet healthy dishes, specially for Karan and Robs (my fussy men).

9. Do a holiday with Robi ...alone, just the 2 of us.

10. Catch up on reading and sleeping.

Anyone have any more suggestions? Or wait let's just see how many of these things I end up getting done. Or wait, let's just see if the leave gets approved. Isn't it fun to day dream?
