It's usefull and very excitingThe good thingsI enjoy a lots of things in my experience are working with other people and different types of mindset culture and dealing with defferent kind of religions learning how to understand communicate, and i also learned the little things how to appreciate it.
The challengesFor me Maam/Sir not totally not enjoy because in my career we need to strong, just a little of sadness homesick, Yes that are the parts of being far in your families i advice that we need to be strong to take all the problems in life, God is Good all the time
