Is it very tough to do what you say you will do?

Had a very sad experience over the last 2-3 days. Was meaning to catch
up with an old friend and some who i really respect both personally
and professionally. He missed two phone appointments and finally we
ended up leaving things open ended to catch up over the weekend when i
am back in mumbai. Whats alarming is not that he missed calling me
twice on preset times but that i genuinely feel this person must not
have had the time to do so. I find it all the more shocking is i think
the person is in senior management. I am in senior management and as
far as i remember i have been multi tasking with a very busy schedule.
However, i always keep my word. I dont have the time, i wont schedule
a call. I schedule a call. I will make it. Its something i was advised
by someone and i intend to follow. Do what you say you will do. Simple
principle and something i feel leaders must abide by. People who dont
do what they say they will do can be great contributors but dont make
great team players. Imagine a basketball team where the star player
never follows team strategy. An air force formation, where one pilor
decides to take that turn a bit earlier, the sales guy who always
tries to go after non named accounts. Do what you say you will do. Its
a simple way to live your life.
