Do bear in mind Mani that although the money is higher in London so is the cost of living, but if it is something you'd like to do, do it.
I moved to London when I was in my early twenties, basically for the same reason, money. The degree I had was in fashion, and that's where the jobs were. I had a great time, it's a fantastic city, with everything you want to do, at whatever time of day.
Do also consider that with nearly ten million people, it can still also be an incredibly lonely place, I was lucky already having friends down there. I reached burn out after seventeen years, and downsized to Glasgow for three years, before eventually realising there's no place like home.
