It goes without saying that this is probably going to be one of the hardest experiences of your entire life, if not THE hardest experience. But it will also be one of the most rewarding ones when you get to the end of your training and manage to get a job that is going to help a lot of people. There might be times when you feel as though you want to give up, but know that if you have got through to the training stage then you ARE capable of finishing it, and you simply need to push through and get to the end of your journey.
