Planning just before retiring

There is a silent fear when we are near the magic age.. on how the next many years will be .. how the lifestyle will be and how to continue to be engaged in a good way

Retirement is not only about ensuring you have the right level of money to ensure a good lifestyle, it is also about how to be engaged in a fruitful way so as to not degenerate away. 

In our working world we are very very highly engaged.. Our life is our work. I know I work 15 to 16 hrs a day, with weekends also being mostly engaged. 

Unfortunately from such a hectic lifestyle, once a person retires, he/she has plenty of time in their hands with mostly no idea of how to fill it.

Here's what I am thinking of doing as I retire over the next decade.. 

1. Do some consulting work with large companies

2. Write a book

3. Join an NGO and help out to expand 

4. Maybe participate in the local politics

5. Be healthy with an active lifestyle

What about you.. What's your mantra
