What skills do I have that other people would actually pay for?

The question most people ask is 'what am I good at?' That is the wrong starting point. The right question is: what do you do that other people dread, avoid, or do badly?

Start with what you already resent doing for free

If colleagues keep pulling you aside to explain something, ask you to review something, or fix something they made a mess of, that is a market signal. You are already providing value. You are just not charging for it.

Go back through the last two or three years of your work. What problems landed on your desk because someone decided you were the person who could handle them? That pattern is more honest than anything you would write on a list of strengths.

The narrower the better, at least at first

You are not selling yourself. You are selling one repeatable outcome. A report that takes someone four hours and takes you twenty minutes. A process that always breaks in the same place and you know how to fix it. A translation between two departments or disciplines that nobody else in the room can do cleanly.

Broad skills, 'I am a good communicator,' 'I am organised,' 'I think strategically', do not close. Specific, demonstrable outputs do. The more you can point at a concrete thing and say 'I can produce that, reliably, in this timeframe,' the easier it is for someone to hand you money.

The trust is already built in the industry you know

Do not try to sell to strangers first. Sell to people who already know how things work in your field, because they can immediately recognise the value of what you are describing. You do not have to explain the problem. You do not have to earn credibility. The shared context is worth more than you are giving it credit for.

Start with the sector you came from. Offer to solve one specific problem. See if they say yes. If they do, you have your answer. If they do not, ask them what version of it they would actually pay for, that conversation is worth more than most market research.

One practical way to find the answer this week

List five things you have done in the last year that produced a clear result for someone else. Not tasks, results. Then ask, for each one: does the person who needed this have it again in six months? If yes, you may have something repeatable. Repeatable is what you can charge for.
