Navigators do not choose a heading first. They take a fix — a measured position — and only then plot a course. Choosing work to do alongside a full-time job benefits from the same order. Below are four readings worth noting before you pick any direction. None of them predicts an outcome; together they show where you are starting from.
Reading 1 — Free hours
Write down, every evening for two ordinary weeks, the hours that were genuinely free: not commuting, not caring for someone, not recovering from a demanding day. Most people find the real number is smaller than the number they would have guessed. Use the measured figure, not the hoped-for one.
Reading 2 — Fixed costs
List the bills that must be paid every month regardless of anything else: rent, utilities, transport, debt repayments. Your main salary should cover these on its own. Side income is irregular, often delayed, and sometimes zero; counting on it for fixed costs turns a small experiment into a source of stress.
Reading 3 — Skills
Note what you already do well enough that someone else would reasonably pay for it: editing, translating, bookkeeping, repairing, teaching a subject. Separate skills from interests. An interest can become a skill, but that is a longer voyage and should be planned as one.
Reading 4 — Energy
Mark when in the week you still have attention left. Some people are sharp early on Saturday and empty on weekday evenings. Side work placed in low-energy slots tends to be slow, error-prone and quickly abandoned.
Plotting a first leg
With the four readings written down, a sensible first leg is small and reversible: a limited test, a fixed number of weeks, no up-front spending you cannot afford to lose. Write down in advance what would make you stop. Stopping after a test is a valid result, not a failure.
Limits of this method
The readings describe your starting point; they do not tell you what to do or what you will earn. Contract terms, tax rules and family circumstances can override any plan. Where those apply, see our notes on employment contracts and fees and taxes.
