I think it is important to keep positive in the moment and realize that you shouldn't beat yourself up for your mistakes. I made the huge mistake of leaving Dave's keys in an Uber... but in the end, it was really an interesting experience, and I think Dave and I definitely grew closer as friends haha! The important thing is that you keep your head up, and deal with the situation you are faced with, without dwelling too much on the past. It's important to learn from the past, but not to be hard on yourself about past actions to the point of not being able to function in the current moment.
When the car as we know it today was first invented, it was called the horse-less buggy, because they didn't know what to call it! They figured, well, it gets us around, and it is a buggy without a horse... We are at that stage with electric vehicle technology. We are calling them 'electric cars', the same way that today's cars were once called 'horse-less' buggies. However, just as ridiculous as 'horse-less buggies' sounds to describe today's cars, it's the same thing with electric cars.
