Humans are strange. Whether we are brilliant at what we do or not we all like to feel indispensable. I like to feel that way and in fact I thought that I was indispensable in every aspect of my life.This feeling keeps me going, it keeps me driven and alive and I am insistent that no one can do what I do they way that I do it. But then you get ill (as I am) and you are forced to lie down at home with your email from work as your only tool. It is in this state of incapacitated illness that I have realised that no one is indispensable. Absolutely no one. There are many people who can do my job even though they might be unhappy at the prospect of doing my job, they still do it.My point is this: Take time off when you want to because life is not about becoming indispensable.Becoming indispensable is impossible and that is reality. Everyone is replaceable in any job even the president, hell, especially the president should be, can be and is replaceable. I also think that it is necessary for companies to occasionally remind their employees that they need to perform consistently well because if they don't there is someone else who can do the same job for less pay.
