When writing an essay, always begin by drawing a mind map (google it if you don't know what it is). Consider the causes of stress then evaluate ways to overcome it.
pressure from studying - have a break, have a kitkat. - don't study long hours if it is tiring.
First thing you must write is the introduction. The introduction must introduce your reader to the topic on hand. In this case, it is best to write the meaning of stress and its ultimate effect (e.g. suicide, depression, unproductive lifestyle). At the end of the introduction, introduce the topic.
Stress is a physiological condition which challenges or pose a threat to our well being. Stress is often viewed as an unhealthy condition but it is often overlooked that stress also causes a person to do something. However, when a person accumulates stress, it may cause him or her to experience depression, be unproductive, and it may even lead to suicide. Students experience stress as often as a tiger eating its prey, which is pretty much all the time. Due to this, students must handle and manage stress as efficiently as possible to continue doing well academically. The question is this, how do we cope with stress? ~ Don't copy my introduction, I put effort making this, you should too.
Always encourage yourself to use similes and metaphors as opposed to idioms and big vocabularies because students often misuse them.
Then you can go into the first content of your essay. Lets use the example (first example) I gave above.
To explain ways to cope with stress, the root of the problem must first be identified. One of the causes of stress is studying. Studying in itself is not bad but it is well known that too much of anything is bad. The pressure from studying may cause stress. In order to cope with the stress caused by studying, the person must learn ways to manage it. If it is tiring to study long hours, then the person should learn to study shorter hours as being more stressful does not help a person study. The person should also take breaks while studying so they can vent the stress before moving on to the next topic or homework. ~ As I said before, put your own effort into making your own paragraph.
Rinse and repeat the process and voila, you have an essay ready to be reviewed by your teacher. Except that it is lacking a conclusion. Conclusions should be kept short and snappy. Don't beat around the bush, get straight to the point, slam it in their face. The conclusion should always refer back to the topic discussed. In this case, it is 'how to cope with stress'. Restate the topic then conclude it. You may even include your wishes in there.
Stress is not the monstrous abomination everyone thinks it is. It is very manageable and quite easy to cope with. Stress-induced ailments and psychological states can be prevented with the right methods. Therefore, as students, we must not falter to stress and keep striding forward to a future worth living.
Just one little tip, never use the word 'I' in an essay unless you are writing in first-person.
