I have run into many versions of limitation in my life but they were usually self-imposed. This is a result of allowing irrational fears and doubt to overthrow my confidence and belief. I began to change after the first time I heard a well known analogy:
To keep an elephant in place, handlers use small ropes tied to the ground with tiny sticks. The elephant can easily break away from the rope but it does not. That's because when the elephant was younger and smaller the same size rope was used to tie them and, at that age it’s enough to hold them. They try to escape for a while and eventually give up. When they are older and stronger they still obey the limitation, even though it no longer exists.
These days instead of accepting that I’m tied down; I’m never afraid to tug on the rope a little. I often find that my limitations are not real, just a baby-elephant-like conditioning.
