Must you be an expert on a subject in order to compose a written document about it? This is certainly not correct. You can write on any topic, as long as you sincerely believe in your desire to express your opinion. Smile as you write. It helps to positively frame your thoughts.
That said. How do you begin to write? If you are not sure if you have the confidence to write, no matter, just start to write, or type. The words will begin to take shape on the page, letter by letter, one idea after another, until you have your masterpiece. Yes you can successfully write, even if you do not have any experience.
Before you start scribbling out your thoughts, you might want to focus you mind on a topic of great interest to you, about which you can passionately write. Now consider what you want to say about it. What would anyone else say in contradistinction to the ideas you are presenting. This is it, clearly. You have a method for great writing. With each thought, consider a counter-position. Like stitching a quilt, patch by patch, eventually you will have a complete embroidered work of art.
As you begin to compose your written masterpiece, consider your audience. You might want to use vernacular or plain language, simple terms or more professional terminology for the specific area of interest. Perhaps you might wish to discuss your ideas a few times with industry professionals through an online business networking platform or group and take scrupulous note of any comments on your ideas. Also, search online and in trade-related magazines to see what is currently being written about your topic of focus.
But write as often as you can. The more often you do it the more easily you will be able to create literary works of art. Have confidence that your ideas are important and relevant. Soon it will become second-nature or a regular part of our routine. Once you begin to receive comments on your written contributions – no matter what replies you receive – consider them as constructive criticisms. Proudly write and know that your expression will be a great value.
