Where did my time go?

It is impossible to live without failing at something, unless you live so cautiously that you might has well not have lived at all, in which case you have failed by default.”
Joanne Kathleen Rowling

Making decisions is a hard job for everyone, but we have to.
Delaying decision making is at the root of most of the procrastination generated in this world. There are many times when we have a lot to do and we have to choose one to start with.
So we make a list of all the todos and start choosing process.
Thinking, evaluating, judging, masticating, maybe over-thinking, thinking about something else, and something else, someone else.. browsing SNS,chatting, stalking…..
And when we come out of that cycle due to slammed door or alarm clock..poof..times up!
We end up not doing anything, which is catastrophic, as JK Rowling above describes it you have failed by default.
Here is my two cents to solve this problem:
Its better to start with something which is independent of other tasks and get started.
By the time you are midway and are worrying about something other on your list ask yourself :
Can it wait till completion of the current job?
If No : Can the current job be paused? if No, then continue with your current job till it reaches a position where it can be paused.Then start with the other one.
If Yes: Continue with what you are doing. If it is difficult force yourself to do it, you are building your concentration muscles.

Starting something will keep you away from the above mental-cycle initially, but you will have to constantly fight the urge to switch between tasks.With practice it wont bother you.
Sometime there is a temptation to multitask. Multitasking is not for humans due to overhead of switching time.Please avoid it.
Crossing out items from a todo list is very satisfying experience. If you have not done it lately, try it  and let me know how it went.

On a different note that is somewhat similar to how our laptops/mobiles CPU schedules tasks to perform.
