To think about the others...
I often go to the countryside to pick up some home made food as it has no chemicals therefore is better for health. When I get home I take it out to eat it. Then I think about my family. I'd rather give everything to them rather than staying healthy myself and watching them die of cancer, blood vessel or heart or other deseases. But they never appreciate food like that and never think about difference in food and consequences of consuming one or another product.

Sometimes I find stuff brought by me and left for them rotten, since nobody even touched it. This is when I feel, like I've lost a fight to some evil forces or so. Then I think of God and nature - a great father and mother in heaven. I imagine myself in their place and that I have a child like me - devoted and faithful. I take care about this child and give him the best that I have - best food and clean water. And what would I do if this child would give all that to somebody else who ignores me? This is the point, when I understand, that it's ok that I eat all by myself.
