When it comes to writing any story or essay, there are 2 things you can do. Either tell them or show them. The difference might seem small, but can have a huge effect on what comes across to your reader and their reading experience.
I usually relate this difference to feeling a paper. When someone is showing you in their paper you can feel them in the paper and the paper becomes more realistic to you. But when someone is just telling you stuff, well it just seems like information you must now try and remember.
When you tell someone you are cool, they are not just going to start believing you. They will need to experience who you are and what you do for them to truly know how cool you are. So how would you do this? Show them, share experiences of things that happened and that you did. You can even show them by using some imaginary or description.
When it comes to describing something, use your words in such a way that it paints a picture not just describes the picture. Example: It was cold outside. Well this sentence is boring, but change it up a bit. The frost crystallised the windows as we sat inside, curled up in your warm thick blankets.
The human brain is amazing at remembering feelings, so is the reader can't feel your writing, the chances are that they will forget a lot of what you said in your writing.
Thought provoking questions, this is one of the best things to use in a paper. Instead of you painting the picture with words, you guild the reader to what you want them to create in their own mind using these questions.
Combine all of this together and your reader will feel you and love what you wrote. Leave that impression that will last a life time on your readers. Make them feel your writing and who knows you might of just change their life just by helping them feel your writing.

Just on a little side note for self improvement. I will be doing pushups, situps and squats for the amount of $$$ (ratio;$1:1) I earn on this post and will give a short feedback every day at the end of each post. This will be split in equally between all 3. Any not done will carry onto the next day.
