I was 23 when I actually got my license, so I was a bit older myself. Despite driving before getting my license, I was very nervous when it actually hit me that now I have the responsibility of paying costs associated with having a vehicle, and the fact that I had to drive fulltime. My nervousness went away about a year driving my own vehicle around.
When I look back at all the equipment I’ve had to learn to operate on many of my jobs though, driving a standard highway vehicle seemed something silly to be nervous about. I still get nervous driving at times, especially in more populated areas, but I’m still glad that I drive. I live in a rural area too so I have to drive.
