What influence us to make a financial decision is best known to us but most times they are things we spend most of our time with. So of us will always love to share this decision with our colleagues or friends just to hear their opinion on it. It is not as if they know better than us or we can't make decisions ourselves but we know nobody knows it all and we can't always get it right.
One mistake that people always do at the beginning of their financial journey is having too much confidence because even when people are advising them to let them see the fault in their decision they won't listen which sometimes leads to regret but as we grow we wiser and have a better understanding on how to make our decision.
Some people don't have anybody they share their decision with but grow with time to make better decisions based on the failure they made and learn from that failures to improve their chances of getting it right but these can waste our resources, time and effort and that is why we share our decision to avoid this long journey and sometimes we have people that has been through the process around us which have the knowledge and scars, we listen to them because to avoid common that people make.
Evaluation
There is nothing bad in listening to people but the mistake we will make is not doing our extra research. Sharing a financial decision can save us from a lot of stress and can help us in making better decisions. some of us get it right by just having people with better experiences around us. These people help in guiding and mentoring us. We should not be ashamed or scared when we want help but also be ready to do it better.
