Work is a lot like having a run or jog.
When you get started, you find it difficult to get going. Lethargy sets in. You start wishing for your nice little warm bed to lie in.
You start your morning off in the office. Lethargy sets in. You laze around, not really wanting to start work.
Then, when you're all fired up and going, you just keep going and going. Your legs have a life of their own, carrying your body further and further. Time is always your enemy. There are always competitors and mind games to battle.
As the day progresses, you get your stuff out and keep doing your work. Your brain starts thinking faster and faster about the things you need to do, the emails you need to send out, the people you need to call. Time is always your enemy. There are always competitors and political games to battle.
When you are nearing the finishing line, your adrenaline steps in and pushes your body to the limit. You gasp for breath, but keep sprinting for the finishing line because it signifies the end.
On your last few days before your annual leave, you start clearing your work. On the very last day, you work really really late because you can sleep in and relax the next day. Your body is screaming for rest and food, but your brain keeps you going, keeps you thinking, keeps you working.
Then you stop suddenly, and your body can't react fast enough to cool your body down. You walk around, trying to relax all the tense muscles and catch your breath back.
On the first day of your leave, although you don't need to work, you wake up early as usual. You surf around, pace around, walk around. Trying to find things to do, things to occupy your restless mind, things to relax your mood.
When you try to run again, the momentum is lost and you have to build it up again. Rinse and repeat. The cycle comes in a full circle.
When you come back from your annual leave, you lost the momentum for work. You have to build up the mindset again. Rinse and repeat. The cycle comes in a full circle.
