Bottleneck

As per usual, I look for something in the James Clear email I think is useful and is, from my experience, a truism.
I liked what I read when he said, “avoid being your own bottleneck.  If you lack the skills, be willing to look foolish while you learn them.  If you lack the connections, be courageous enough to reach out and build them.  If you feel uncertain, be bold enough to figure it out along the way.  Many people have the ability, but they talk themselves out of trying."
To me one of the greatest hindrances to achieving all I would like to is fear and a lack of self-belief.  It seems so easy to me to talk myself out of something as I cannot see myself doing it or going there.  It is so frustrating when it is a dream of mine to go there.
In that instance I need to determine why I am the way I am.  It seems that often to me it is accepting the limiting thoughts of another.  “No one in this family has ever done that.”  “You need a good dose of realism.  Stop dreaming.  You’ll get hurt.”
There are many ways one is put down and discouraged from giving it a go.  It is interesting to me the word discourage has courage in it, but the dis is against it being exhibited.  I will never forget the Ziz Ziggler story of the fleas.  They were placed in a bottle with a lid on it.  They jumped as high as the lid.  There came a point where the lid could be removed and the flees would only every jump as high as the lid and there was no concern that they would escape.  They had been conditioned to the point of going no further.
For me it is like talking myself out of trying.  Becoming my own bottleneck.
I need help to reach my potential.  Growth always means going beyond limits.  Yet so often the limits I set are based on my own perceptions and have nothing to do with my potential.  As far as I am concerned, I get one shot at this.  I may as well give it a go.  I’ll never never know, if I never never go.”
