What are the important things to take (other than documents) for traveling as a girl alone for the first time?

I'll be travelling alone in a few weeks alone for the first time and not sure what to carry with me? ( on a road trip, not plane).

Where are you going and how will you get there? We need context before any answers can be given.

How far are you going?
Where are you going?
What for?
How long will you be gone?
