You will never be totally sure when making a decision. Even the most accurate risk analysis won’t be perfect and most of the time, you won’t have all the information available. On the other hand, time is a crucial factor in the decision process. There is an opportunity which has a limited period. You cannot take too long.
To make things more complicated, risk factor is positively associated with growth possibilities. This means that when facing decisions that involve high investment (time, effort and money) and when outcomes are uncertain, is when we potentially grow more. One question that it might be helpful in the decision process, is what could happen in the worst scenario? What will I take with me if the outcome isn’t the expected?
Nevertheless, the above doesn’t mean that you have to risk all you have. You might want to save some just in case, so you can start over again from a safe point.
It took me years to decide travel abroad to the United States, leaving a secured job, friends and family behind. I invested almost all my savings and took a huge risk. I was terrified. But at the same time I was convinced that it will be worthy and an extraordinary learning experience. Well, I wasn’t wrong. I’ve been learning tons since day one.
Playing safe is easy. It gives a sense of familiarity and comfort, which everyone likes. But staying there for too long, is also risky. You might end wasting many opportunities to grow.
