What matters doesn't really matter afterall

We were on our way home after our dinner last night and this topic popped out and it starts us into discussion.

What matters,most in our life, to us?
In retrospect, I have not given this question any serious thought. I go into each individual day believing that all my loved ones , my work, my habits matter pretty much the same to me. But in the long run- what will actually matter most to me ;I think I have not arrived to a conclusive opinion or even given it a swish.

Everything that revolves around us changes. And with that in tune, all our life priorities change. Subsequently, even what values and principles you cling closely to , may deviate.

Say for example, a few years back, I will work even on Sundays just to ensure that I have a certain amount of money at the end of the day. Anything and everything else comes secondary. Whenever I lost a deal to any competitor, I take it with a foul mood back home. It affects everyone and anything else. Just last week, I lost a deal and I brushed it off rather quickly as there are still thousand and one deal out there to grab. I just went out to Little India and had a rather nice weekend ,not taking it out on anyone.
I see this as the largest change in myself through out the past three years.

I think in our path of life, we find more important things in our life that matters than before and some less important one to discard. There is no affirmative life priorities. At least not in mine.
