Wanting what I cannot have

I have noticed that I have felt dissatisfied at different times today.  Whenever I'm aware of that slightly frustrated feeling of things not being right, I stop and check in to see what's really going on with me.  Then I notice this common refrain: "I want".  But the things I want today are not easy to attain.  They take time and money that I just don't have right now.  In terms of money, I may never have the money required to fulfill many of my wants, such as travel, buying books, collecting art.  I have spent a lifetime learning how to live a satisfying life with less.  But sometimes, the things we want are not discounted 60 or 80%.  It takes real money, and lots of it, to do some things.  That is the source of my frustration today.  It isn't realistic to think that I will be increasing my income dramatically in the coming years.  But I don't like saying to myself that I'll never travel to these places or be able to buy this piece of art, because I don't have the money.  On days like today, it sucks to be able to live a comfortable life--but only if I watch my money very carefully.  How I wish money wasn't an object and I could do all the things I have always dreamed of doing.  But then what would my dreams be?
