Drift of Focus in life! How important is it?

I have been wondering recently about my job. Job is not bad, it is not hard work, it is not insanely intelligent either. I lack motivation, may be since it is not something I want to do. Does work always have to be enjoyable? Or is it that you have to learn to to develop interest in uninteresting things?
Interests change as you mature in your ideas of living life. When you see there is a better side of life, you run towards it. I wonder if it has to do with living in different places, meeting all sorts of people. Having said that, I always thought i don't want to just earn so that I can pay my rent. Money has no value in itself, it is just a means to an end.
There has to be more to life. Don't ask me what is more, I have yet to find out myself. :)

Well, I am not too happy with my work place not being very green. Green in the sense, environmentally friendly. Having said that, I cant find much food in supermarkets which is grown locally.
A friend recently was discussing with me about an article she read in a magazine about the person who bought all local food and went through the hardships of finding his way through a long winter. Well, when Tescos, Morrisons and Sainsburys or say Asda(Walmart in UK) is having so many offers on foods from abroad, it is a tough call to go and find your food from local dealers. Or may be it is worth a try.

I must admit that I am very influenced by the clippings shown on the television about Mother Earth calling for calamities due to human race. I also have started using ecoballs for washing clothes instead of washing detergent. It works fine. Many such alternatives have been doing well recently in my apartment. I admit that there are some things I find difficult to change, habits have sunk in and there is a limit to which you can change your life style. Is it really worth all the effort? Am I going to make a difference in the life of Mother Earth and the future generations?
