I always liked computers, since the spectrum days, in the mid 80's, but my family was very poor and education was not a priority, so I left school at 16 and joined the army at 17.
Done one tour in Angola and one in Serbia, left the army after 5 years and came to London looking for a job.
Done all sorts, from washing cars, working at Pizza Hut, and doing warehouse work.
A colleague at Pizza Hut gave me the best advice ever, which I will pass on to you.
Study, get some sort of qualification on what you like to do, a degree even, and things will work out. Obviously this was before the school fees issue. 🙂
I got into the OU and done a degree in Computer Science, and have now been working for a online gaming company for the past 8 years.
I build and design Datacentres, and I am also a Security Manager, lots of travel, more computers that I can throw a stick at, and love coming to work every day.
If you like photography and aquariums, then concentrate on that, figure out what you need to do to get better at that.
There are for sure degrees in photography and apprenticeships, also there has to be some related aquarium courses you can take in the mean time.
Look at Mr. Amano, aquariums and photography. 🙂 Need more?
