I never realized how what actually happened matters comparatively little to how happy we can be. Till the day I walked out, sore in mind and body, after I had shown my dad the test results on my math paper. And found sounds of celebration and revelry coming from a classmate's house, sweets being distributed and the said classmate being practically treated like an all-conquering hero. My astonishment knew no bounds when chocolate was thrust into my grasping hands and the reason for the celebration was trumpeted into my unbelieving ears.
Huh! For the results of the SAME math test? A test which he had managed to pass by a whisker while I had failed to hit maximum by the same whisker? Ye Gods! How could a pass mark cause so much happiness here while 95% convulsed my house in sorrow?
Oh, I don't mean only the happiness to my classmate and the sorrow to me - though, at THAT time, I was thinking only of that. There is no real doubt that my dad WAS gloomy that day himself and my friend's family was ecstatic. Though, merely going by the marks on the test paper, you would interchange the destinations of the happiness and the gloom.
And THAT is why I say that what actually happened matters little to your happiness. What matters is what was EXPECTED and what really happened. Happiness is a consequence of reality exceeding your expectations and disappointment is a given if reality falls short of your expectations.
So, there you go, my dad's expectations were not met, my friend's dad's expectations were exceeded. Comes the time when YOU set the expectations, it's good to remember this. If you promise your boss, say, that a job will be done in 3 days and you do it in 4 days; your colleague promises to do it in 5 days and does it in 5 days, guess who is the under-performer? YOU, of course, and no amount of wailing that you did it one day before your colleague will help. Your boss may agree, at that time, but the impression of you being an under-performer will STAY, especially if you continue working the same way.
As with spouses, too. The spouse who ALWAYS forgets her spouse's birthday gets away with an indulgent 'memory like a sieve' comment. The one who forgets ONCE will be faced with a 'You don't love me any more'. All because of expectations.
Your expectations are what determine your relationships in life. Expect too much of the people around you and you will find that all relationships disappoint you. And then you may well wail about 'false friends' about the same people that others praise for being very helpful.
Happiness IS a consequence of reality exceeding your expectations. Specifically, it is what you GET out of life which you have expectations about. Money, power, fame, recognition...THOSE are the subject matter of expectations, generally. So, a life is happy if your expectations on ALL fronts are exceeded. (Provided, of course, you do not keep changing the goal-posts, as happens too often. As you keep climbing the social ladder, you keep finding that there are more rungs above the one which you had originally aimed for...so you keep climbing...and climbing...and climbing...and when you have no choice but to stop, you look yearningly up at people on the rungs above you and feel disappointed with your life.)
The easier way is to SET the expectations lower. Which is not really a lack of ambition, only a reorientation of it. Set your ambitions to what you can learn and do and be(character, NOT position)...not what you can GET.
Me? Ah! Well, my dad did always say that I had NO ambition!
