Undoubtedly, if someone has the ability to not be caught up in what is going on around them, their life will be far better than it would be otherwise. They will be able to stay centred and to be the 'calm in the storm' so to speak. This will allow them to stay focused on what matters and to do the things that will bring them happiness and fulfilment. Still, this doesn't mean that they will never be affected by what is going on externally; they are human after all. Another Point :- What this also doesn't mean this that they will lack empathy and the ability to put themselves in another person's shoes. But, although they will be able to do this, they typically won't let what is going on for another to take them out. If a friend or a loved one was not in a good way, it will probably be a lot harder for them to stay centred. However, they might realise that feeling bad is not going to serve the other person and that it will be better for them to be at their best.
