Hey there.
I know success stories comes with a lot of struggles too.
I think the right mindset you need to input yourself now is,
carving your own path.
Everyone's path is different and it's how you would like to get
yourself there and finding out the interest and most importantly,
to be happy in what you do.
There's people had to succumb to certain types of jobs because
it pays them well but some are not happy in what they do but do for
the sake - support family? financial issues? etc etc.
Everyone struggles eventually, if or not how high their
education certs that they have. There be some setbacks in your life
and you have to overcome that hurdle.
I have a bunch of friends that only holds an n'levels cert and
also struggling as well.
Some even gotten a stable job even though because of cert, they
only been paid at a certain amount but they are happy in what they
do.
You can always opt for options for a private diploma and theres
reputable private schools and need to do research on the school
etc.
What i can suggest is, try working for awhile and discover
yourself and what you would like to make as a career and what you
would like to study and focus on that direction.
Sometimes the things we plan wont go our way, but do the things
you don't regret doing than regretting choices you never try in the
first place.
All the best.
