Realize about our thoughts

Throughout our lives we internalize a set of beliefs about how things are, this beliefs are consider like holy truth and guide our behavior and our thoughts in a non-concious way.
Most of time we behave by habits and make quickly judgement with lttle information, our brain is structured to make patterns, habits, routines, both in actions and in thoughts.
The set of beliefs guide our everyday life, they are our beliefs about anothers doing, what we can do or not, how we are... all this deal our behavior and social relationships.
We use to explain our behavior after, we are an story makers (and we make it really good).
We can detect our beliefs paying attention to what we use to say, and what we use to do, what is important to us, what anothers make that really upset us, what it's usually said in our family.... our beliefs come from our close ambience
To reflect on moral sistem, why we feel something better or worst, the cultural use (like meal times), trying to understand why anothers think the way they do. We don't have to say like a reason to do something "I make it because I think so..." We have to try to find a really reason why something is better doing than another... if we decide to make it because we think so at least we know that there are options the same good.
We can develop a more rational system of beliefs which would help us to live happier, more concious, more responsible and over all more respect with us and the rest of the people, we would get things by negotiation and reason, not because we are stronger or shout louder.
Most of limitations are on our beliefs not in the reality, in general anybody can get anything they want, one astronaut is a human being with trainning, simply somethings take more work than anothers.
One psychologist very interesting to read about destructive beliefs, feelings and behaviors is Albert Ellis who develop the Rational Emotive Behavioral Therapy, he found out that there was some beliefs on the base of a lot of patologies.
I'll give your an example of erroneus belief without importance to point how easy they are generated:
"When I was younger and learning to cook, my mother explain me thay chickpeas should be soaked on hot water and boil without salt or they would not be cook. The beans are soaked on cold water and boil with salt or they would not be cook. As I'm very disobedient and incapabe to make a recipe as it is on the book I didn't make like my mother told...... and it happen nothing, the chickpeas and the beans cooked even if they were both soaked in cold water and boiled with salt (and very tasty)
It's interesting to realize what really matters and what are simply different ways of making
Human beings make relations of couse and effect very good and sistematic, it's on the base of our way of learning, it's very useful but it can give often superstitious behaviors.
To use our intelligence to analyze and evaluate our beliefs, habits, actions.... will help us to be more happy.
