I've lived and worked across 19 countries so I can probably answer this question much better than anyone else here.
Travelling isn't overrated. It's the best thing any living organism with legs and ability to travel faster can do. I've been a very introvert person throughout my college life. When I landed my first job which was a small startup of 48 employees (including the founder) we were expected to do everything. I got my first travel opportunity to Kuwait in 2014 where my customer was literally located on Kuwait Iraq border guarded by the US marines. I spent 6 months here developing a HR and Payroll software along with a BI application. I made some great work relations with people from different nationals. We lived together, cooked food, went around exploring Kuwait city. I learned alot of life lessons and became really extrovert in nature. I made tons of mistakes since I wasn't aware about the etiquettes of dealing with different nationalities.
Once I was back after my stint I was sent onsite again this time to Dubai in the UAE to work with a public sector customer to implement a costing and profitability system as an ETL developer. I was there for 3 months and Dubai is one of the best cities in the world. Whatever they do they thrive to be world class. Having learned from my previous experiences, I learned and networked with alot of other nationals and locals alike. I even explored around Abu Dhabi during the weekends. Following that I got many such assignments in the Gulf especially in Bahrain, Qatar, Oman, Lebanon and Jordan.
Our VP decided to give me a new region and sent me on a project to France in 2016 for a one year long stint where I learned French language and even had a French girlfriend. I traveled all over France and explored many places around Europe and the UK. I was also put on another project in Portugal for a few weeks. I explored this beautiful country in under 3 weeks.
There's so much traveling has taught me and made me who I'm now.
