A note from the creator

High school student · creator of Career Guidebook
I built this because my friends and I face enormous decisions. College, major, career direction. It's a real challenge to know what to do when the consequences last a decade. Most information is fragmented: spread across government reports, industry surveys, insider forums. Nothing pulls it all into one place that's actually useful to navigate.
So I compiled it. For every career: what you'll earn at each stage, what school actually costs, how the field splits into different paths, and the specific decisions (internships, exams, gap years, recruiting cycles) that shape everything downstream. The goal isn't to tell you what to do. It's to put the real information in front of you while you still have time to use it.
I should be transparent: this site looks at education and careers through one lens. Return on investment. What you pay, what you earn, how long it takes to break even. That lens is useful. But it's incomplete.
School matters for reasons that don't show up in spreadsheets. The conversations you'll have. The mentorship that changes your thinking. The weird skills you pick up in unexpected places. The people you'll actually stay close to. These things compound over decades in ways that are impossible to quantify upfront, but almost impossible to overstate looking back.
So here's how to use this site: use the data to avoid genuinely bad bets. Don't borrow $200k for a $45k job. But once the numbers work, let other things matter too. Go where you'll learn the most, meet people worth knowing, and actually want to show up. That's real returns.
Most salary figures and growth projections come from the U.S. Bureau of Labor Statistics Occupational Outlook Handbook. BLS doesn't track investment banking, private equity, big-law partner pay, or founder outcomes, so those come from industry compensation surveys and are labeled as such on each career page. Tuition ranges come from NCES data. Break-even math assumes about 15% of entry-level salary goes toward payback each year. Salaries shift, school costs move. Use this as a starting point, not financial advice.
