As we get wrenched in our super tight schedule, we get less and less time for the important things to do in our life. We got almost every one of our resources in a limited amount and TIME is no exception.
Opportunity cost of time
Let us understand this concept with an example. You have to buy some item A and some item B in a limited amount of say $ X. If suppose A and B cost the same then, increasing amount A or B will directly influence the amount of the other item.
In this manner, when we try to overcomplicate things by dedicating a large portion of our time to the things that are really not productive, we're actually reducing the time available for the real work.
We can really put this concept into a formula
If ACTIVITY == PRODUCTIVE { Do the activity }
Relative Productivity
Most people do not realize at the start of the day that much of their work revolving around the main work is really not worth it. They mainly spend their time doing work in smaller portions with some occasional time period of concentration which is distraction-free.
While realizing that we can carry out most of our productive work during a certain longer and continuous period of time and can use the later time for rest and slightly unproductive
Objective Productivity
There is no such thing as objective productivity. It differs from person to person and there is no one fits all formula for this. One thing that may be productive to you may be completely unproductive to some other person. All the hyper-hyped techniques like Pomodoro and meditations are really not productive but can be helpful to increase your time concentration while you are at work
The formula for increasing productivity is really relative and more often than not, depends on the goal to be achieved. In fact, productivity is only achieved when you have a clear goal in your mind.
