I have grown a lot over the years in this subject.
It took and still takes.. practice, different experiences, and more practice to feel grateful for what I do have, and allow it to be enough.
But not only that, having gratitude really helps me be genuinely happy for other people when good things come their way.
Happy. Not bitter, jealous, or sad.
How much easier it is this way. :)
I get to bypass all that junk of emotions that I used to feel, and just feel happy for that person. Because Hey! They deserve good things!
When I do catch myself feeling self pity.. Because that's what it is really.. it doesn't help anything! And of course all I want to do is vent to someone.. but guess what.. no one wants to hear someone whine about how unfair life is. Now I can catch myself when i start to feel like that... I stop. I really think about what I'm feeling... how silly it is. And I literally think about what I do have. And it is so much. My life is full. What I have now.. is completely enough. I am blessed.
Things happen at different times in everyones' separate lives. And it's a beautiful great thing.
My time will come.
