Anything that immobilizes you,
gets in your way or keeps you
from your your goals is all yours.
You can throw it away anytime
Dr. Wayne Dyer
What Wayne Dyer is saying in this quote is that whatever circumstances you find yourself in, you and only you, have created them. No outside force has put you in this position - no matter what they said or what they did, it is still your choice how you respond. You are 100% responsible for how you handle whatever is thrown at you.
You can always change how you conduct yourself... it is not mandatory to react as you always have. If you pay attention to how you handle circumstances that cause you stress or pain, you will start to notice the things that could be changed. Don't spend any more time worrying about things you cannot change, don't spend time worrying at all, it changes nothing.
If you find obstacles in your way, work on finding out why you are creating a situation that keeps you from going where you want to go. There is always a reason and it is always about you. Only you can make the decision to stop self-sabotage.
Don't be too hard on yourself... even though you are a spirit having a human experience, you are here because there is a lot to learn and it all takes time.
"If you change the way you look at things, the things you look at change." Dr. Wayne Dyer
