When the fool appears in a reading, it usually shows some kind of wishful thinking. It also shows the very early, beginning stages, new start or jumping in too fast- immaturity.
The fool means innocence and naivety. It will show up if you’re trusting too much or not trusting the right people. (reversed)
On the flip side, it can show that you’re getting ready to start a new chapter in your life- a new beginning still in the immaturity stages. (right side up)
If you’re reading the fool in a love reading, it’s showing that a brand new, immature relationship is going to begin. It can symbolize puppy love, the infatuation phase. (general, right side up)
It could also be warning you that you’re not seeing the full picture. You’re naive and foolish for going into a relationship like the one you’re entering. (general reversed)
If you see it in a career draw while considering leaving a job or starting a business, it could mean that you’re plans are not thought out well enough and that leaving will be premature or the business isn’t thought out enough yet. (reverse)
It could also show that you’re getting ready to enter an exciting new phase- so it could be telling you that now is the time. It will all depend on what the rest of the cards are telling you in that reading.
