Hi,
Engineering = Maths... unfortunately, maths is the basis of engineering/design... Maths is the tool of engineering... A degree is the hardest and will cover maths in very detail. A diploma course will still cover maths but in less detail. A technical course will still do maths but cover even less in detail. So you can still do engineering with different maths level potential.
As an example - to drive a CAR you need not know much about internals workings of car, to be a mechanic you'll need to know quite abit about the internals of engine etc, to design a vehicle you'll need to know all of it... so enginnering has similar layers...
If you like to design something, you
have to decide what kind off thing, where does your passion lie with designing.... Civil engineering structures, mechanical, electrical, computer, chemical plants, Marine etc etc... Choose one only and focus on that field of engineering. Watch you tube videos of different enginnering fields and evaluate your passion.
If you intend working in an engineering field at the top most level you will have to be very good at maths and do a degree course at a University where you study and do practicals. You have to be very good at maths as designs are based on calculations all the time. If you just want to be part of an engineering team you can do diploma/technical as a senior engineer will 'take care " of the maths.
If you really want to do engineering, give yourself another chance at liking MATHS, maybe try again with an open mind and more diligence. There are many internet learning channels and videos which explain maths concepts. Identify one field of engineering you have a passion for and read, watch videos,download books and see if thats is what you like/want. You can even buy books used by colleges/universities from university bookshops (new/used)and learn what you can, as knowledge is cumulative.
As a career you need to be really good as it's a responsible position so naturally the best person will get the job... You can be employed as an engineer, technician etc so the future is what it is... Sometimes a hobby in this field can also be fullfilling... must carefully choose as not all fields of engineering has great work opportunities and its a dynamic job market....
