"From Your 40s, Have Two Income Streams" by Jin Sakashita. I've only read it once, so the inside is in relatively clean condition. However, there are some minor stains and scratches on the cover as shown in the photos. There are no folded pages or writing. Please only purchase if you understand that this is a used item and has been stored at home. Please check the condition in the photos. This book is recommended for those who want to try a side job, increase their income, or rethink their way of working. #BusinessBooks #SelfImprovement #SideJob #IncomeUp #WorkStyle #Book
