What do you have to gain?
The cost of not becoming what you could have become is always greater than the cost of the failure from trying. I think if we were able to live in a way that minimized regret, and that we were able to understand the true benefits and costs of long-term consequences, we would be happier for it.
Sometimes if we give up an opportunity in favour of staying safe, we are failing to realize the potential gain from taking the opportunity. Fear of the unknown is rooted in all our decisions.
The next time you make a decision, do so by considering what you have to gain instead of what you have to lose. Because while we may be able to quantify or specify what we have to lose, perhaps it is our inability to quantify what we have to gain that prevents us from taking the risk.
The reason why we are considering the decision in the first place may be because of the fact that what we may have to gain is far greater than what we have to lose.
