One of the life skills that will help you always, no matter what career you are in, is to be diligent.
For example, I work with people in at least three time zones at the moment, and each time before I send a calendar invite, I verify what is the time in my time zone.
Even though I have memorised the time differences, if I schedule an hour here and there it would lead to unprofessionalism.
Something that could be avoided with a tiny check of 10 seconds.
In life, we want to do big things.
That is great.
But the things that sustain the big things in the long run are taking care of the small things in the short run.
Anyone can reach the airport on time for a flight to JFK.
But can you reach your Mom’s home on time on her birthday?
The small things (invisibly) create the big things.
