I was just wondering that how much a relationship matters to _____!!

Its possible that I might deviate from the main theme..The theme that I have left incomplete.
Either a 'ME' or 'US' will make the theme more relevant.
But this article would some how revolve around the topic only with or without an 'I'. Cause the area is so vast that its tough to include everything.. May be for an amateur like me it obviously is...so let me begin with..

Heartbreaks...
If you don’t have a sound mind.. I mean to say if you are not mentally tough then no one can save you from heartbreak, till you don’t recover by yourself.
Life has its own way of teaching things and what I believe is "good things come in small packages and we need to enjoy them to the fullest. Even if the relationship is bad or takes a wrong turn... It has got to be for some betterment. May be to make you tougher or may be an indication that it wasn’t the right time to fall for someone.
Or may be _______ this “may be” can differ from person to person.
Now the problem above is something inevitable.. I feel there are things which are far more important.

Apart from love and affairs, there are other relationships...And they hurt equally...In fact they further aggravate the sourness already there cause of other relations...though the only consolation is that these relations and people stay there in life.. But it’s possible that your love interest may not be there forever.

I just wanted to ask - which is more important - people who stay in your life forever or people who are there for a brief period of time??
Long back I read in TOI about relationships. And the article talked about three types of people who come in our lives -
1. Mirror images - those are just like you and resemble in everything just the way you are..
2. Then there are people who come for a short period of time.. Make your life beautiful, guide you through many difficulties and then part ways. But they are the ones who in a short while give your live such a beautiful meaning that all that can be done is wondering and nothing else.
3. Third type resembles with us to a certain extent, but not completely.
(May be a little vague, but I have just given the gist of things)

What's the importance of people?
We can’t measure this thing... Today we are so prone to using people that we don’t event think twice.
But we do blow the trumpets everywhere that, "I love my mom or I love my Dad", but if we look deep down we know that we don’t listen to either when it comes to leading life the way we want. And today’s youth is least bothered that what their parents or relatives are thinking about them.
Today I get back from my college and I hardly have time to be with my family..why?
Because I am another workaholic on the block - one who loves her work. So many assignments and projects.. and then it makes me act like a nerdy, although I am not one..
My brother gets back from work and has no time to listen to all the crap I have stored through out the day..somehow this makes me a bit pissed off..but I know that the office pressure is far worse than my college pressure. Thus I comply with the situation and carry on with the schedule. I guess my dad had a pretty good office timings..he gave us time and made us successful in career. He gave the necessary platform and we carried on with the rest.
Friendship - once in a blue moon we get someone who is really worth to be called a friend. But ya today we have a huge list of friends... whom we proudly proclaim to be friends..But we hardly share that touch..And at the end of the day we know that they are good for nothing for us.
World is selfish...so are the people in it...Whom to spare and whom to be with?
The question remains there... may be this is my confusion that I am sharing... or may this is the truth that I feel is evident everywhere....
And at the end of the day when I get back to myself - I usually wonder what matters the most to me?
