  In the UK it takes around 3 years, sometimes you need more time. Each person has a different journey. Like everything you do in life, if you put your heart and mind, fully to it, it becomes easy. I’ll become a real doctor soon (not a medical doctor ;). I took 3 years and 2 months to submit my book called thesis.
