I'm going to read the books which were on sale that I bought last year. The first book is It's Okay, You're Just Different by Kim Doo Eung. I've been reading this book since last month. Yeah, I'm a professional procrastinator🥲. Let's just finish the book this weekend. The book is about how certain mothers raised their children who later became fabulous people. You might know these people. They are Thomas Alva Edison, Picasso, Einstein, etc.
Besides that, maybe I'm going to do some exercise, such as running and playing badminton. I've started playing badminton since 2 weeks. Don't expect too much. I'm a noob player. I'm so grateful my friends are so kind and patient to teach me how to play badminton properly. I don't even know the rules😄. I've realized that my skin gets much smoother and the stretch marks are going to disappear. That's cool. I thought I already lost some weight, but sadly it's still the same😅. Nevertheless, my skin will be glowing up and I feel happier. To be honest, my psychologist has diagnosed major depression to me (or "diagnosed me with major depression"). She has recommended that I do some exercise. At first, I didn't believe it, but I've been doing what she has said and I think it's working!
Changing the order of the ideas in the first sentence will make it flow a little easier: ¨I'm going to read the books that I bought last year when they were on sale.¨
¨I've started playing badminton.¨ is grammatically correct on its own. But because you added a specific time in the past that this happened, it needs to change to ¨I started playing badminton two weeks ago.¨
You've done a nice job with your writing. You seem to know a lot of colloquial phrases and you use them correctly -- noob, glowing up and (my favorite) professional procrastinator.
The book you are reading sounds interesting. Biographies in general are great -- and the focus on the mother who raised these exceptional people is an interesting angle..
