Feeling of being unlucky

Today while randomly searching i stumbled upon a quote "People are lucky and unlucky...according to the ratio between what they get and what they have been led to expect." I found it very interesting and hence was quick to share my discovery with others through the obvious path, Gtalk status message. Since these are not the good times for me as far as mental peace is concerned hence it was not uncommon to think a bit extra over it. Most people and me in particular always crib over the things that we don't get and in most cases we blame it on luck. Luck being the unlucky savior bears the brunt of everyones failure. I once saw a animated series in which luck was portrayed as some kind of living character and it gave the justification over the things, that were blamed over him, I had found that amusing as well as revealing a truth. I often consider myself to be highly unlucky and that too to the extend that if someone has to choose 9 out of 10 people standing, I am sure i won't be the one chosen. This feeling of bad-luck has held me in the captivity of negativity (I just love this phrase, thanks Cole phifer aka T-Bag). After reading this quote (the earlier one and not the one by T-bag) I think this gives a better picture of what luck is. In most of the cases we consider ourselves unlucky when we have a case in consideration to whom we consider "lucky". The whole comparison thing brings in the good luck or the bad luck. However in those situations if we see everyone, than definitely we will come across someone, in whose comparison the person in question is lucky. Sounds a bit confusing but it is the truth. I am not advocating that whenever one feels down one should compare ourselves with someone in a miserable consideration and than feel happy about it that I am not in that condition (I utterly disagree with Mahatma Gandhi in viewing everything in this manner to infuse happiness in life) Rather I am saying that instead of comparisons one should see the things in absolute terms. The burden of expectation from self is the major cause of the feeling of failure which when happens repetitively leads to the feeling of being unlucky.
So the thing is if I don't expect so much from myself, the feeling of bad luck will disappear. So for the case of deferred joining in which case i consider myself highly unlucky, if I wouldn't have expected myself to be working by July/august, I wouldn't have considered myself unlucky! But this argument further digs into the negativity. To curtail this feeling of luck (or bad luck) one shouldn't expect anything from self. This lack of non-expectation will kill away the motivation that is generated from the raw desires fueling self performance. This would further lead to under performance and thereby underachievement but possible mental peace and happiness as you won't feel that you have been deprived of luck. I think this would be more dangerous proposition than the one in which I am presently in. As in present scenario I always think that this time I was "unlucky", maybe next time I will make up to the lost opportunity. It may sound to be idiosyncratic but it is not, think over it and definitely you will realise that its better to consider yourself unlucky than being potentially happy by eliminating this luck factor in the above mentioned way. So Mr. Luck, this quote won't do any good to you and as always you will be blamed for every failure that I undergo in future.
Do you agree with me or consider this whole argument not strong enough and the quote to be much stronger? If you disagree than I think you must be one of those lucky chaps and thereby the ones who have undermined their potentials in their own thinking, hey dude wake up.
