Hello, I'm a copy editor and proofreader by profession. I read your blog and found that I could help a lot in improving its clarity, cohesiveness, content structure, writing style, and language. I reworked on the first paragraph of the blog and pasted it below, for your reference. I made the changes on track and inserted comments for you, but then only realized that Freelancer doesn't have an option to upload documents. So, I'm just pasting my edits of your first para below. If you do not prefer such extensive work, I could do basic proofreading too, as you wish.
"It is not very easy to find a mentor who could assist you on your professional development. So, if and when you do get a mentor to work with, it is important for you to understand ways in which you can get the best out of your mentor. But before that, let's briefly review the differences between a coach and a mentor. A coach is someone who you engage with in learning a new task, or improving your performance in an already known task. In both these cases, the coach would usually have expert knowledge in the concerned subject. For example, your coach may teach you how to use a new application at work. Coaching is usually a short-term job-specific activity where you observe your coach at work, learn from them and then try to put the acquired skills to use."
