If I should answer this question, I would say I have been practising writing skills as one of the purposes of this blog. However, I am not saying I have developed it. Instead, I am developing it. I do not thing everything can be developed to a perfect level in life. The same is with writing. There are a lot of pitfalls of it – you need to improve your grammar, your vocabulary and your style, especially if English is not your native language. I try to find different topics and interesting questions every day that can spark an engaging discussion. I try to share my opinion and make my posts as long as necessary. It is not easy though. I need to think a lot, I need to think about the details and how to write about it.
It is changing my life, yes. It is my side job. I write for this blog but I also have some other websites where I write articles. I do not expect a large profit from these websites but I can say that writing influences my life in a way that it is part of my free time. I just try to be productive.
