self doubt when training

In the last few weeks in teaching at the academy, I have noticed more and more of the new students getting frustrated in their training. This could be on a techinque or missing the focus pad on a combination.
Now we all get frustrated from time to time, whether it be in training or in life,but what we are actually doing is putting the first seed of doubt in our minds.
Like a plant seed this doubt seed will slowly grow then in time will grow faster to the point we give ourselves the excuses to stop training.
Even the expereince students still have to stop this self doubt process, it is a constant battle with ourselves and this is the beauty of the martial arts, the battle within ourselves, to improve our internal thinking and to see when we plant the seeds of self doubt we correct it.
One way to combat self doubt is to stop in that moment and say it's just a mistake and that's how we learn by mistakes. Congratulating yourself on recognising this process, like ying and yang always look for the opposite, ie negative counter is positive like sparring if your opponent expands you contract.
In sparring you learn a lot about yourself, do you defend more then attacking or do you attack more then you defend,our characters come to the fore when we are put into sparring mode without warning.
To all the adult students at the academy there is a sparring workshop on Saturday 9Th October see in the academy for times and check the website.
Self doubt remember is the start of excuses think about the cold nights when you have to leave the comfort of your home to go training, need to think about it? That's when self doubt takes control if you let it grow.
It's LEAVES ARE EXCUSES.
