Stephen Covey in his book The Seven Habits of Highly effective People' suggests that you begin with the end in mind. This is so important when you retire as it's too easy to while away the days getting very little done. But come to terms with the fact that you may not get things done quite as quickly as you did when you worked; you may be much better at mixing leisure with tasks/ 'work'/things to be done.

Make the plans, develop the big vision. Decide what might stop you and what your very first steps must be. Then commit yourself to doing those first steps….you are on your way to having the life you want after work!!

When you have recently retired you can be very active and do so many things, so get moving, get going with them while you have time and energy on your side.
