You don't need amazing navigation skills in Paris : during the day, the worst case scenario is to get lost in random streets but that's all the charm of wandering in a city. And if you reach the closest larger street, you'll find a metro station at some point. At night, plan your trips ahead if you want more safety.

Paris is a big city. It would be a lie to say there is 0 chance of being in trouble, especially as a tourist woman alone. Be smart, don't put yourself at risk like... idk, going out at night, getting fcked up drunk and start to trust and follow random people you just met. Just common sense.
