Are quick decisions always wrong

Are quick decisions always wrong?
I do not agree to the point that decisions made quickly by people are
always wrong. In fact I believe that fast decision making power is
gifted to only few person who as a result spearheads various areas.
These type of people can make use of opportunities by making fast
decisions while others just sit in ambivalence. People having this
ability gets edge in social professional and personal life. This can be
observed with example in everyday life
Sometime there are situation where person have to think fast and
come to an immediate conclusion. People making fast decision
handles these type of situation with excellence. Consider a situation
when there is a road accident. All type of people surround the area
but person who is able to understand the situation fast make people
shift the injured at the side of road so that it do not block traffic,
calls ambulance, search for identity of the person to inform his
relative, intimates police and takes other necessary steps. Others are
seen either standing stupefied not knowing what to do or obeying the
instructions. This way people capable of understanding the situation
and acting accordingly takes command of any unfavorable
unanticipated situation and proves helpful to society.
In today`s throat cut competition where there are less opportunities
and more contenders, people who are among the first to understand
the change in market trends captures markets and are seen as market
leaders. Because of ability to think readily and give fast solution
these type of people poses themselves as leaders and are
unanimously selected as leaders. So fast-thinking people are
benefited professionally too.
This way I believe that people having capability to make fast
decisions have advantage over people who make decisions with
careful thought.
