To choose a career, you first need to decide what to base the choice on. No matter how many aptitude tests you take, without a basis you will not know what to do with the results. In most cases, what is missing is not information but a standard.
There are three main standards: what you are good at, what you can do without getting exhausted, and what conditions you want to work under. If you choose based only on what you love, you will not last when the other two do not fit.
Which of the three comes first differs from person to person. When you need income right away, conditions come first. When you are choosing a field to work in for a long time, the one that tires you less comes first. Setting your priorities naturally narrows your options.
Treating it as a choice between the two gives no answer. You find out what you love only by doing it, and what you are good at shows only over time.
There is a more useful standard: whether you can keep going when things are not working. Love for something fades when things get hard, and the sense of being good at it weakens too, but a field you can keep working in stays that way even then.
They are useful for narrowing the direction, but they cannot name a specific job. It is common for people with the same results to do completely different work and do well.
What these tests tell you is how you are most comfortable working: whether you prefer focusing alone for long periods or working with others, and whether you prefer set procedures or something new each time. Using this information to choose a way of working, not a job title, makes it far more accurate.
The only way is to try it on a small scale. Talking once with someone who works in the field, doing one short project, or attending one related meetup is enough to see how different your expectations are from reality.
Collecting information while putting off the decision usually does not help. The more you look into it, the more options you have, while you still have no direct experience of any of them.
You can. And changing does not mean starting over completely each time. Much of how you work, how you deal with people, and what you know about a field can be used in the next job.
So there is no need to think your first choice decides everything. Choosing the best option under your current conditions, doing it for a few years, and then deciding again is better than doing nothing while waiting for the perfect answer.
What you are good at and what environment tires you less need to be looked at separately. Even work you are good at is hard to keep doing in the wrong environment, and even the right environment is hard to stay in if the work is not a strength.
The Beyond Persona assessment reports Meaning, which shows how much you look for purpose in your work, Growth, which shows how much you want to keep learning and improving, and Decisiveness, which shows how quickly you make decisions, as separate results. They can help you judge whether to change fields or change how you work within the same field.
