In our daily life there are so many chores that demand completion. Some of them require no or little thinking while others may require not just thinking but a session of detailed thinking before we are convinced and are able to complete or rather say start it.
Amidst all such thoughts and actions cycle what we may tend to forget is about priority. Unfortunately, the systems around us are all architected in such a way that there are so many issues and problems that do not deserve our attention but we tend to scale them at a higher position in the priority list. Consequentially, these no so important issues or tasks or problems start taking a decent amount of our mindshare and concentration while, considering what their actual significance is, it is best to postpone them and not provide our mindshare to them.
The other way round, we also need to identify those tasks, traits that deserve to be on our priority. Some of them are being happy, introspection, knowing one's strengths etc.
Oh ok, there is no need to think much about this. Just keep in mind the not so important things in life may actually be very important and those lists you made but did not complete may not be that important that you need to loose the peace of your mind and some time to observe this world.
So, we need to Think, Plan and Do. But, the first step, thinking, needs to be of much more significance.
