There are a number of things to consider with a career change. living is number 1. How much money do you need to get by on. Ie, we don’t need sky and all that stuff. But mortgage, rent, food, vehicles all that. Assuming that and you have an idea what you want to move into then qualification needed.
Remember, 2 people go for a job, one qualified and experienced, the other not. The selection panel has to whittle to a shortlist to consider for interview. Which are they going to go for? So make sure you have all paperwork in place. There is no reason why you couldn’t phone up the organisation and have a chat about the work and what they look for in people. This is before a job is available. it helps to understand what they want from people. Linked in is often a good place to get names to have a chat.
also remember that 95% of job descriptions are tosh. Most companies want people to be able to hit the ground running so you need to ensure that you have sufficient experience to persuade then they want to employ you.
if you are going self employed, that is a whole different story and a lot of that comes down to your personality. Some of us are not suited to self employment And are far better off with being factory fodder.
Everybody can change roles. It is just knowing what you want to go far and knowing what the market is looking for and of course the availability of work. I never did make it as a sex god. Apparently I had the wrong features.
Do a lot of research and good luck with what ever you decide.
