What do you believe are some of the other major influences on developing our attitudes toward different things in life?
It is hard to answer this since you say "other" and you do not tell us what influences are already known...
To me the major influence in developing our attitudes towards various things is our family. I am not saying that we end up believing all the things our parents do, but their influence surely affects us in ways that are both conscious and subconscious.
After that, the media surely influences us, depending on the extent that we expose ourselves to things like TV shows, advertisements, etc.
A third thing I will mention is peers. This becomes more important as kids get to be of school age and especially as they move towards junior and senior high school.
This one will be quite fun to sort through the many responses. I think that the previous post's assertion as to what "other" may be is an important one. I would echo that family and religious values, if present, play a role in determining attitudes towards different elements of consciousness. At the same time, I would posit that art can play a vital role in determining and shaping beliefs and attitudes about different aspects of being in the world. For example, reading literature or watching films that involve individuals who possess similar circumstances to our own might be able to help carve beliefs about what it means to be human and how to better interact with our world.
The major influences on developing our attitudes toward different things in life are: family, social network, and experience. Our family plays an enormous role in how we view things, and it is primarily from them that we receive our values and beliefs. Friends and acquaintances also play an important role, for it is through them that we can take our family values and experiment, change, or adapt them to suit our needs with our friends. Also, our experience in using what works and what doesn't work plays an integral part. These three influences have the greatest impact on our lives.
