How to Choose a Career
"What should I do with my life?" is one of the highest-stakes questions most people ever face — and one they're given almost no method for answering. The advice on offer tends to split into two useless extremes: "follow your passion" (which assumes you already have one, fully formed) and "just be practical" (which ignores that you'll spend 80,000 hours of your life doing this). A better approach treats career choice as a decision you can reason through, using evidence about yourself rather than a gut feeling on a Tuesday.
Why "follow your passion" is incomplete advice
Passion is usually a result of doing something well over time, not a prerequisite you must discover first. People develop passion for fields where they build competence, autonomy, and meaningful relationships. So if you don't feel a burning calling, you're normal — and you're not disqualified from a great career. The more reliable inputs are your interests, abilities, values, and the realities of the labour market. Get those four into alignment and motivation tends to follow.
The four inputs that actually predict fit
| Input | The question it answers | How to measure it |
|---|---|---|
| Interests | What kinds of activities energise vs. drain you? | RIASEC / Holland Codes interest inventory |
| Abilities | What are you reliably good at, with effort? | Track record + cognitive/skills assessment |
| Values | What does the work need to give you (autonomy, security, impact, status)? | Values sort / honest reflection |
| Market | Who pays for this, and is demand growing? | Labour statistics, job postings, informational interviews |
The biggest mistakes come from optimising on one input and ignoring the rest: chasing a high-paying field you find draining (interests ignored), or a beloved hobby with no market (market ignored).
Start with interests, not job titles
Job titles are a trap because they're abstract — "marketing manager" tells you nothing about whether you'd enjoy the daily work. Interests are more stable and more predictive. The RIASEC framework (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) maps the kinds of activities you gravitate toward, and decades of research link interest–environment fit to job satisfaction and persistence. Knowing your top two or three codes turns an infinite list of jobs into a shortlist of environments worth exploring. (Our career interest guide walks through the six codes.)
Layer in personality and ability
Interests tell you what you'd enjoy; personality and ability shape how you'd perform and feel day to day. High Openness pulls toward variety and ideas; high Conscientiousness suits structured, detail-critical roles; Extraversion vs. Introversion changes how much social load is sustainable before it costs you. None of these are destiny — but a role that fights your natural wiring extracts a tax every day. Pairing an interest profile with a Big Five trait profile is far more informative than either alone.
Run small experiments before big commitments
You cannot think your way to certainty about a career — the information you need lives in the work itself. So convert the decision into cheap, reversible experiments:
- Informational interviews — 30 minutes with someone three years ahead of where you'd be. Ask what the worst part of the job is.
- Shadowing or a short project — a weekend, a freelance gig, a volunteer stint in the field.
- A course with real output — not to credential, but to feel whether the daily activity is something you'd willingly repeat.
Each experiment is cheap to run and updates your estimate. Five small experiments beat one agonised five-year guess.
A decision you can actually make
Bring it together in four steps:
- Map your interests — find your top RIASEC codes; list the environments they point to.
- Profile your traits and strengths — note where your personality and abilities amplify or tax each option.
- Name your non-negotiable values — autonomy, income floor, location, impact. Cut options that violate them.
- Test the survivors — run an experiment on your top two or three before committing.
This won't hand you a single perfect answer — those don't exist. It will give you a short list of good options you've reasoned toward instead of stumbled into, which is what a real career decision looks like.
Get the inputs for your own decision
My Path's Career Profile maps your RIASEC interest pattern to occupational environments, and pairs naturally with the Big Five personality assessment so you can see both what you'd enjoy and how you'd perform.
