concentrate on getting good academic qualifications, then you have better career choices later in life where you don't have to work do manual work and the associated health problems that come with age. The career you mentioned charge £50+ an hour round our way and to qualify at university at a later age in life will take 5-6 years and the courses are extremely expensive compared to builders and plumbers courses and similar qualifications.
My father pestered me to learn a trade when I was young,......so I learnt two trades and have several other qualifications as I stayed on at University until I was twenty seven and have travelled half the world in various jobs. Sadly my father is no longer here to help me out but I am so glad he pushed me to gain qualifications. Manual jobs with good rates of pay are not the be all and end all, happy medium of balancing life, work, family and pleasure is the key to a good life.
it's interesting you say that.
i went to university and got professional qualification. i worked in the NHS for 4 years as a healthcare professional but hated it. hated working 9-5 monday to friday. didn't like having managers, having to do what i was told when i was told to. it didn't make me happy
i started my own business and a little later got into window cleaning and now have those things you list as important "happy medium of balancing life, work, family and pleasure"
my friends who work as lawyers, teachers, doctors etc work far longer hours than me, and far worse work life balance
you can make this business what you want, i haven't cleaned a window in 3 years now
