They say that before your body can do something, your mind has to do it first. If you do not believe in something mentally, then - physically - you will not be able to do it 99% of the time. Thus, a proper mindset is very important for maximizing your physical performance. Of course, one needs to focus on building endurance gradually, since your mind can only take you so far before your body really cannot operate anymore. It is in these months/years that you spend preparing for an event that you have to start preparing mentally to do well during the actual event.
Staying in all the time
If you need to be mentally prepared, you need to be involved all the time. This will not only stretch your mind but also keep it sharp.
A Fit Mind
With new things, the human mind learns to stay strong and perform better, because different challenges make your brain act differently every time. Combine fun with learning by reading often and playing a variety of different games. Regular exercise and fitness activities will strengthen your mental capacity.
Reinforcing Mental Function
Developing the right skills to help your mind stay sharp and promote stronger thinking and concentration is also important for good mental functioning. One needs to identify things that distract you and then create an environment that keeps those thoughts away so it doesn’t harm your performance.
Believe in your capacity
You have to be self-motivated and have believed in your capacity to achieve the goal.
