Let's start with the basic:
What is stress?
I like the Wikipedia's answer:
Physiological or biological stress is an organism's response to a stressor such as an environmental condition. Stress is a body's method of reacting to a challenge. According to the stressful event, the body's way to respond to stress is by sympathetic nervous system activation which results in the fight-or-flight response. Because the body cannot keep this state for long periods of time, the parasympathetic system returns the body's physiological conditions to normal (homeostasis). In humans, stress typically describes a negative condition or a positive condition that can have an impact on a person's mental and physical well-being.
Our focus here is more on the negative impact of stress and furthermore on the ways to minimise it or the keep this impact under control.
Here is a short list of my self-approved
methods to deal with stress:
Mindfulness — in my opinion the best preparation for meditation sessions
A few exercises are already online. Try them, step by step, the first day the first, second day the second, the third, the fourth, and so on.

Meditation — headspace or everything meditation practice that you enjoy
Sport — whatever you like, but do it at least for 30 min and at least twice a week.
A small portion of stress, which boosts your adrenaline, train your mind and by the end increase your self-confident. And real confidence is the best preparation for facing a stressful situation. It helps you to be good at stress like Kelly says.
