Could you correct my mistakes, please?

I used to think of myself as of quite an adventurous person, always ready to accept changes that were big or small, whenever they knocked at my door. I’ve moved to different cities 3 times. I’ve lived abroad and I used to hitchhike every summer. Life they say, starts at the end of your comfort zone. That’s true, but it’s not the only possible outcome as it can end there as well. So I would say there’s some kind of misconception, as comfort zones provide security, and that’s what makes living possible and keeps anxiety at bay.

I’ve come to a  the conclusion that my cravings for change are basically rooted in boredom. Being stuck in a rut is rightly associated with stagnation. On the other hand, as most people I’m scared of the unknown like most people. It’s not easy to make important decisions right away; cold turkey style. But probably (I would choose slightly different wording here, maybe: "However, ") there’s no need to turn life on a dime chasing adventures. Traveling, taking up a hobbies, meeting new people, sharing, and most importantly gratitude, can ultimately break the monotony of a dull day.

Pretty good overall, have a good day.
