Congrats on starting off your career plans at sixteens that definitely puts ahead in the game.
I am going to add that even when it comes to wordpress you can create your own themes.
You can make each as individual as you wish.
Also you don't really specify what interests you the most, is it design or developing. As it is you'll notice that the more you get into the wider your fields and options get.
Degrees can be good, especially as come companies. (intel for example) want candidates w/degrees. However, they are not always necesary and on the flip side are possible loan/debt loads.
And higher ed can be fun, make friends, network, find new experiences.
A bit early in your life to think you don't have a chance really
work, be creative and fun. Don't just rely on the net. see also who else in your community could use your work.
