Paul McCoy's guide to surviving in BigLaw is written for attorneys, but is just as valuable for paralegals and other support staff. Actually, this book's practical advice is valuable for anyone in ANY industry and can be applied to any aspect of one's life.
Chapters currently bookmarked in my Kindle edition that I have referred to again and again:
Ch. 6: You must understand the relative value of your time to the time of others. - this chapter should be a must-read for ANYONE practicing in law. So many needy associates or self-important paralegals do not understand this concept.
Ch. 8: Train others; The benefits are exponential. - Law, like other high stakes careers, is rife with imposter syndrome and work-hoarding. Because of this and the short-sightedness of those who are withholding training opportunities because "it's easier just to do it myself!" (imagine toddler foot stamping), the practice will stagnate. Train others - yes, it's an initial investment of time that may hurt your productivity in the short term, but the long-term benefits will increase your productivity, and that of your firm/practice group. Withholding does not make you look better and only serves to hinder growth.
Ch. 9: Seek the most complicated assignments. - Essentially, if it's something no one else wants to do; GO FOR IT. You'll gain experience and a reputation for being a team player capable of complex work.
Ch. 14: You are no longer paying others; you are now being paid. - Essentially, keep your entitlement in check. This isn't your college that you're paying tuition dollars to receive an education. You are being paid to do a job.
Ch. 17: Takers & Ch. 18: The art of "yes-f***ing." - essential survival tips and skills for dealing with takers and other toxic/entitled people. This chapter applies to every aspect of your life.
Ch. 25: Your boss is not your parent; your subordinate is not your child. - yet another chapter I wish was required reading for anyone in law. Its lessons are just as valuable outside the profession, but the boundaries and tone-checking are especially relevant in law.
The rest of the chapters are just as important, these are just the ones that really get the most use from me, whether for my own reference or when I need to coach a colleague. If you work in a law firm, I highly recommend you read this.
