Deep down inside, I believe we always know what we truly want. Our feelings never lie. It is a simple Yes or No all the time.
The trouble comes from our rational minds over-thinking a gut want. Some level of rational reflection is a good thing perhaps. But not when it consistently pushes us to prioritise the shoulds over the wants. To subsume our own needs in favour of externally imposed or absorbed priorities.
Too much thinking. Not enough feeling.
