Being risk adverse is often seen as a cowardly way of dealing with life. Perhaps it turns into a list of pros and cons, and then later a list of rules in which to live by. Feeling as though things need to be measured in order to avoid error can become a source of neuroticism. Leaving making a decision especially and unplanned one may cause disruption in life.
There are three different emotional states that can influence decision making: Your current emotional state (i.e. How do you feel while you are making a decision?) Your past emotional state (i.e. How did you feel anticipating your decision?) Your future emotional state (i.e. How will your decision affect how you feel in the future; What effect will the decision have on your emotional well-being?). This can drive someone to not make a decision at all, or once they make one, continue to remake the same decision so the results are expected.
Bringing me to my point about how fear can lead to feeling a strong need to be in control, and stay in control in each circumstance that you can. This can often lead to issues like depression, anxiety, eating disorders, addictions, and overall poor mental health.
Which brings me back to the question "What are we giving up?" when we deeply want control, to avoid risk, to have nothing unplanned? Off the top, happiness, the willingness to be flexible, cooperative with others, freedom to make a mistake, failing forward, and so many other positive things that can bring more peace.
Yet, those that are risk averse won't allow themselves to experience these things due to the fear of not being in control is so overwhelming.
Here are some things to practice to be less risk averse/controlling:
1. Practice trusting yourself
2. If you make a mistake, remember you are doing the best you can
3. Remind yourself the world won't fall apart when you let go of control
4. Allow others to help you manage things/help you
5. Try something different the next time a decision needs to be made
