It seems that we humans are just terrible at handling ‘big’ tasks. Last week my hard drive got corrupt and I spent a week in what felt like limbo in trying to recover the files. In the meantime however I felt like I couldn’t do any real work!
Right after I managed to fix it (luckily didn’t lose anything) there was another ‘ultra-urgent’ crisis that needed handling. The result is all the day to day admin gets pushed away. You don’t notice it at first but sooner or later you start it feeling building up with a lot of guilt as well.
When you do get your time back, you just don’t know where to start!
Sometimes we take on a project that we become almost obsessive about (i.e. it eats into your personal time) and you carry on doing it for hours at a time while delaying other important things. We could be doing it for fun (a hobby project), or we could be doing it out of emergency, or being too goal focused (to get it out the way). This is fine for a while, but the problem with these time-consuming tasks is one loses track of when to cut off and revert back to other things. It is important to not lose sight of that cut off limit.
The result is you lose sight of prioritization skills, and not to mention forgetting to eating properly! (Smaller regular meals).
It seems we lose track of being able to keep everything in our heads if we put too much emphasis on one task. That is why there is real value in dividing a task into smaller manageable bits. (I’m sure everyone can identify with taking on something that spans more than a day and then feeling disapointed when you don’t finish in the time you set yourself). So divide and conquer and try to organise your work in a way that is more fulfilling for yourself.
