I have some great news and some puzzling news for you.
If you want to change your world, you can. But you can't change it by trying to change it. You change it by changing yourself and changing how you view your world.
"Change the way you look at things, and the things you look at will change." Wayne Dyer.
You have power, probably more power than you know. But your power lies in your ability to create and recreate everything inside yourself. And in doing so, like an ongoing ripple in the pond, you'll affect everything and everyone around you.
Nothing ever happens TO you, it happens FOR you. Look for the lessons, for the learning, for the growth. Life is always helping you to advance. So get better, not bitter.
I changed my world when I stopped expecting folks to act the way I wanted them to act. Heck, that just kept me waiting, upset and stuck! Releasing my expectations for things to happen in my way and on my timetable set me free.
Set yourself free by Flipping it! No one owes you anything, so get clear on what it is you want in life and know that "if it is to be, it's up to me".
Think for a minute about who and what are in your world. Your partner, your income status, your friendships, your possessions, your success or lack of...it's all a product of you. You alone attracted them, invited them, lured them and settled for them.
The happier you are with yourself, the happier you'll be with everything and everyone around you. And positive things will begin to happen on your behalf.
