The short answer
01 · The source
Write down what you want to leave: the subject, daily tasks, hours, management, or pay. Then check whether the new industry would change that part.
02 · The size
A new industry may bring new problems to solve. It can also keep the parts of work you dislike. Compare real jobs, not the name of the field.
03 · The move
Read several real job ads and try one task from them. Note what still interests you after doing it, not just before.
Separate what changes from what travels
Write down what you want to leave: the subject, daily tasks, hours, management, or pay. Then check whether the new industry would change that part.
List the skills you could use at once and what you would need to learn. Ask someone doing the work about a normal week, the hard parts and how people get in. One person’s view is a start, not the whole picture.
Speak to more than one person if you can. One employer or one role may not stand for the whole field.
One case
Say you want to leave marketing for teaching because you like explaining ideas. Teaching can give you that. It also brings prep, paperwork and a fixed timetable. A short spell of teaching would let you compare the daily work first.
Test the difference
Read several real job ads and try one task from them. Note what still interests you after doing it, not just before.
If the change hits your income, compare real costs and real pay. A chart cannot show demand, whether you qualify, or what you can afford. Bring the question of what you want to change into the read. Check the practical rules on your own.
