Planning doesn't mean scheduling

I read this problem description in a mail this morning:

When I plan perfectly for the day ahead, I sometimes find that I am not able to implement all that I had planned for. Things seem to be coming up unexpectedly spoiling everything for me. I am then not able to be happy with what is happening and so find it difficult to do my best in the particular situation.

A solution was given in the same mail:

It is as important to be flexible in my thoughts as it is to be particular about my daily schedule. Flexibility allows me to accommodate the unforeseen situations that come up my way and enables me to make the best use of everything. And so I enjoy everything that comes my way.

The solution might sound simplistic but I sense they are right in emphasizing the importance of flexibility in any schedule. Forget the long term planning, planning 'precisely' on a daily basis like the time-table of classes in a school or an assembly line factory doesn't work for most individuals.

An important aspect of this planner, Cockpit, is that it doesn't make you do precise slotting and scheduling (though the option is always open) but it does aid immensely in listing just the important things you would like to accomplish/execute in a day's time.
