You can perform best in competition if you remember the following pointer:
Enjoy the performance - if you find it dull, then you may need to psych
yourself up or focus on performance rather than outcome goals. If you
are so stressed that you do not enjoy the performance, implement stress
management techniques.
Execute, analyse and improve skills in practice. In competition perform
thought-free - trust all that hard training. Only analyse your performance
after the event.
If you make a mistake during performance, forget about it and focus on
executing the next skill properly. Dwelling on past mistakes will distract
you from good performance of present skills.
