What do you want?

Well I have read so many self help books and heard many people say the best way to lead a good life, is to know 'What you want in life'?
This question appears very simple. Many times I have heard people say first decide what you want out of life? Out of life? Well I asked my self what I want? Honestly to tell the truth I don't know.
If the answer to this question were simple then every body would be leading a good and contended life, but looks like every body's life is becoming more and more complicated more so because they want this, that and more and what not.
Well having asked the question let me try to answer this.
Is it materialistic question that the answer should be I want a House , a car or what ever, but it looks so stupid that every time you see a better model of what ever you want, you lose interest in the one in which you have and aspire for the one which you don't have. So this is not the answer.
Well I can say I want peace of mind and happiness. Well it is too general an answer that I think almost every body wants that.
Well my answer may be specific and if I could just say I would like to go in a particular direction whether career or in home front. But I have reached a certain age where I know many a times, life does take lots of twists and turns and however much you try , you are like the drift of wood which has to take the direction of the water current in which it is floating.
Some times we keep thinking what if? Questions. There are two roads and had we taken the other road what would have happened. But it is always futile question and you will never know the answer as you have already taken a particular road and traveled a long distance. (I remember there was one movie in Tamil '12 B ' where the director tries to answer this question when he shows both the options of the hero taking the two alternate roads, but this can not happen in real life)
What ever we want on daily basis also keeps changing on daily basis. Some time you want to be all active and go out and meet people and be an outdoor person do lot of outdoor activities. But some other times, the same you just don't want to go anywhere but just sit and relax or sit and be moody. But this also is a phase and it just blows over.
Well I resolved the question my self and decided not to answer this question and let it be a question mark always and to take life as it is on every day basis and bottom line is be happy and try not to hurt others and be helpful .
