We all fantasize about money. All of us.
If we have $50,000, we want $100,000. If we have $100,000, we want $1,000,000.
It'll never stop. You'll always want more than what you have.
Now, there are many, many, explanations for why. Some explanations are spiritual, and some scientific/psychological. Most of them are valid (or at least sound valid).
Either way, there's greed involved.
However, do we ever stop and appreciate what we have? Because, we would have appreciated the $100,000, if we went back to $100,000 in the previous scenario.
Most importantly, do we appreciate our loved ones?
I want you to picture the person (or people) that matter to you the MOST. These are the people that you argue with, but can't stay mad at. The people that you can be yourself around. They're the ones who if something happened to, you'd destroy the world for.
Would you trade them for what you're "greedy" about? What you lust after?
Would you trade them for $1,000,000, this very second? What about $1,000,000,000, or $1,000,000,000,000,000,000? Would you offer them up if the devil gave you that option?
I bring this up, because we don't think about things like that. It's already common knowledge that people don't appreciate what they have, but generally we're talking about materialistic things. However, the most valuable thing, after God, is family.
So, appreciate your family. Appreciate your loved ones; your children, your spouse, your parents. Love them, and show them that you love them.
