On Friday, you were the person people trusted to get the work done. On Monday, they’re looking to you to decide who does what, how the team will communicate, and what happens when work gets stuck. The promotion may be well deserved, but the responsibilities have changed faster than your habits.
A new title rarely comes with a calendar full of instructions. The 90-Day Leadership Field Manual, written by entrepreneur and leadership adviser Haraya Del Rosario Gust, is designed for precisely that gap. Its day-by-day sequence gives first-time managers something practical to work through as they begin leading people, rather than expecting them to assemble their own training from scattered advice.
Your Old Strengths Won’t Run the Team for You
Being good at your job probably helped you earn the promotion. Perhaps you were the person who spotted mistakes, rescued deadlines, or knew the answers when everyone else was stuck. Those strengths still count, but using them exactly as before can leave you doing your old job and your new one at the same time.
