How do you stay calm and collected when playing if the tensions are high? Maybe order a drink? Listen to good music? Have a tried and tested routine down to calm your nerves?
I take a deep breath and if possible take a drink. I can also take a break for fresh air before proceedingย
I would try to remind myself that it is important to have self control. It can be easy to be affected by emotions which will only negatively affect your gameplay even more. When playing it is always best to remain objective and to put emotions aside.ย
