All's fair in love... determination

I was watching this drama last night... one of the characters told another that all's fair in love and that one should go for what one wants...
sure.. you should compete with others for the one that you like... however, fairness aside... if the one that you like is already attached... would you still go on competing? Is that morally right? If the one you like is forced to be with someone else or is unhappy with the other then by all means, go fight for the one... however, if the person chose to be with the other, then obviously there's a liking for that other and vice versa.. so wouldn't it be selfish to go attempt to break the couple up? I'm sure if you are attached, you won't want anyone else trying to get your partner away from you right?
That's why "all's fair in love" is not exactly true... unless you are cold hearted, i'm sure no matter how painful it is to see the one that you like with another, you won't want to go fight for her... this might sound cliche, but as long as the person is happy, you will be "happy"... "happy" not for yourself.. but for that person... and you will choose to spend the rest of your life standing in the corner watching out for that person...
Another thing about this determination part.. it is said that if you are determined.. you will get whatever you aim for... obviously this is not true when it comes to stuff like the above case.. or lets say you are determined to stay healthy for life... sure.. you may be very determined.. but then our dear friend up there decides to give you some wonderful present... like say cancer.. you'll still end up terribly ill... so this determination thing does not cover everything.. it all depends on whether you are meant to have it or not... if you and that person are meant to be together.. you'll be together.. if you are not.. then no matter how determined you are.. you will never have that person.. sometimes in life... that's why sometimes...instead of telling yourself that you will achieve something no matter what... why not turn the other cheek and let go... it's hard and painful to do so.. but like i said.. whatever is meant to be.. will be...

Fresh start..

I have finally cleared all my previous posts at last... have been wanting to do so for a long time but was just too lazy to do so... I did this because i wanted to start everything afresh... wat happened in the past is history... focus on the present and decide on the future.. that's most important... learn from the past but do not cling on to it... if you let the past weigh u down.. there's no way u can move forward.... the above is just a thought.. not directed to anyone in particular...
