When we talk about practice we are talking about a usual repetition of certain processes according to a plan we set. For example, if I want to be a marathon runner then I have to follow a program for my training, for my eating etc. These specific activities have to be followed for a certain period of time.
Then, whenever you have been in these circumstances I am sure you should have noticed that after some time you start following your program automatically. You don’t even need to think what you have to do and it has become a habit. Maybe you have increased your boundaries and now things you used to think as unachievable, now look accessible. If you just keep following these activities then you are getting closer to your goal.
