We here have no gap year, nor the money to travel around the world. Anyway, I also spent a lot of my life in the evil comfort zone. But also, I tasted what challenges look like when I crashed my just bought car away from home. I worked with incredibly high effort to settle the things and remain calm. And all that time I had to cope with enormous amounts of guilt and even self-loathing (I have underlying mild mental issues, yes). But I settled all and solved most of the things relatively quickly. This helped me learn the power of our brain and how it can handle ubiquitous stress waves coming from abrupt events like the said car crash.
