If you have an exceptional idea that can make your work done, Don`t hesitate to do it and also don`t rely on what others say, just restrain all other thoughts and behave like a robot. Love your job, reward yourself as always, and the most important is never forget to take a break. Good luck!
It seems to me that when you really do what you like, you can not even take breaks, because this is not work, but just your life, which you like. So why do you need a break from the lifestyle you like?
