Emotions are powerful tools that can assist us in beginning, continuing, and valuing what is good when they align with your purpose, but they don’t always align with your purpose, and quite regularly point in a different direction altogether.
You want your emotions in play when they help you achieve your goals. You don’t want them around when they make life harder than it already is.
It is possible to feel absolutely terrible while doing exactly what will best advance your purpose, and it is also possible to feel amazing in the moment you are acting as opposite as you can to your purpose.
Future feelings can only be maximized through present exercise of reason. Reason alone can accurately gauge long-term cost and benefit. To maximize long-term joy, you have to develop the ability to accurately predict the future and the discipline to choose the path of greatest long-term net benefit, even when this requires choices that presently feel much worse than alternatives.
