Sometimes we kid ourselves into thinking that we aren't successful because we don't know the right people, or we don't have the right education or training, or we don't have the proper tools.
To be sure, having these things help, but they aren't entirely necessary. The best resource you can have for any endeavor is your own experience. The more experience you can draw from, the better you'll do.
However, if you're just starting out in any kind of new thing, and you don't really have any experience, you may feel stuck. You may feel like nothing you will do will be successful. It may seem safer to stay on the sidelines and not making any foolish moves until you know the layout a little bit more.
Unfortunately, this is a comfortable trap. Once you convince yourself it's safer to NOT take action, it's pretty hard to move out of that comfort zone.
So, what do you do? The first thing is to go "meta." This means take whatever you are thinking of doing, and step up on "logical level."
For example, if you are starting a
sales job, and you need to talk to potential customers, it may seem scary if you think of them as customers. You'll look into your memory and find zero experience of talking to customers, which can easily make you feel intimidated.
But you've certainly talked to people before, right? Strangers also. Every time you've ordered something in any kind of food service place, you've talked to a stranger and gotten what you've wanted.
The next step is to literally force yourself to think of those successful outcomes when you're in that new sales situation (in our example). Will this be a magic and quick fix? Of course not.
But you're training your brain to work in a different way. It won't happen overnight, but it will be a lot quicker, and a lot easier than if you just forced yourself to talk to customers, while thinking of them as customers.
The trick is to hold the idea in mind of them as people, or strangers, rather than customers WHILE you are talking to them.
Most people don't do this. Most people think of them as people BEFORE they talk to them, but as soon as they make a move, they switch into "talking to customers" mode.
It can help if you build in some memories (of talking to people) in the front of your brain while walking over there.
Obviously, there's plenty of ways you can use this.
Most other fears are merely psychological, generated by those around us who belittle us or create a fear mentality like the current fear over Ebola created largely by the heavy media examination of the very few cases. They all begin with an unnatural fear of the dark.
You seem to be writing about fear of failure. Instilled in some people by bad nurturing or in some cases, like some members of my family, agoraphobia, now corrected by drugs, as a barrier to success. I agree. Unless one is able to withstand ridicule while trying to learn new tricks, they will not grow and develop but remain stuck in a mindset going nowhere.
