I went to a shop which sells old books. I like to read practical books like ‘how to make time’ , ‘how to make dreams come true by using notebooks’, ‘The 7 Habits of Highly Effective People’ and so on. There were many books I want. I’m worried about whether to buy these. I decided to buy something but I should focus on two or three (at once) at a time as costs are high if I buy many books, even if it’s cheap old books.
