Being brought up in Kenya to Indian parents resulted in the ability to speak 3 languages by the age of 5, English, Swahili and Hindi. I continued this interest right through to my university years when I took on the French, Spanish and Italian. After moving to Bali, I added Bahasa Indonesia to my suite of languages.
The ability to speak different languages has been most useful, as its opens up so many avenues professionally and personally. In addition to this the ability to communicate with staff in their own language always gives you extra brownie points.
