You probably haven't read enough. It really depends on your goals and what you are trying to learn (or whether you are trying to learn at all). Doing is great and it's how you get things done but not everything can be learnt in a few short articles. It also depends on what you are reading too. Reading within a narrow field or an echo chamber can only take you so far. Reading and discovering new ideas can completely transform your entire way of thinking.
Personally, I've set myself the arduous task of mastering English. If you are reading for less than half your day, you will probably never get there with that one.
Written language is a wonderful tool for understanding the past. If you think you know everything there is to know about the past you are indisputably wrong.
If mastering English is your goal, then doing includes conversing. I know a lot of children of immigrants who can understand their parents' language, but can't converse in it.
Where does one converse in English while in a foreign country? I basically taught myself English using the Internet and even though my understanding is top-notch due to copious amounts of reading & watching TV shows, my speech & active vocab are severely underdeveloped.
Get a VOIP/Skype account, find something to sell, phone people in English speaking countries, and sell them it. Google for the expat community in your country if you want someone local.
Apply for VISAs or other things at an English speaking foreign embassy.
Go on craigslist and find stuff for sale phone them and ask questions about whatever it is they are selling. Phone recruiters from craigslist or something.
Figure out something to do that involves English and just do it.
(I think some commenters assumed I was not a native speaker. English is my first language).
Mastery for me would be mastery of English as an art and as a craft. It's about making something people want to consume. Poetry, novels, songs, technical manuals, plays, screenplays, essays, esoteric manuscripts, perfect commentary, and so on. Those are mediums, I want to create something that lives beyond my lifetime. Mastery for me is writing something that becomes truly immortal communication.
