It was a great reminder of what I need to focus on again. The book also offers many recommendations of other books, each useful for developing a specific skill.
A very good point to point instruction or experience talk to entry level of employees, for the advice of work, career and life. Also a recommend to whichever level of the position, some of it must be a good fit to whatever you are facing now. Some book recommend and referral in the book is also a good resource of expanding the career level.
A book which consists a collection of 30 lessons for everyone who has just started a new job as a consultant at a global firm. The lessons are quite interesting and helpful. From the view of an experienced professional, I wish that I had learnt them earlier in my career.
