I have been studying for almost a year, and I study for at least one hour a day; most days two hours per day during several time periods, using different study methods. The only days I have missed studying in the last year was the day after I seriously injured my hand and the day of surgery to repair the injury...oxycodone and serious brain use do not mix.
One of the things I have been doing is meeting with a tutor once a week, to practice speaking among other things. Just in the last few weeks I have felt like I can carry on a basic conversation with her; I am able to express simple ideas in simple terms and am getting to the point where I understand her questions and can respond reasonably quickly. But as I wrote in your other post about fluency, I compare learning another language as an adult to a child learning his or her first language and in that regard I am quite young.
I hope to return to Cuba at the end of this year. At one time I wanted to be "fluent" when that happened. Now I know that is an unrealistic goal and I will be happy to be able to communicate at a very basic level. I think I have at least another 1 to 2 years of diligent study before I will consider myself "fluent," which to my mind is being able to speak, listen, write and read Spanish easily and with reasonably few vocabulary and grammar errors.
A few years ago I was interested in the ideas in Malcolm Gladwell's book, The Outliers, one of which was that true mastery of any subject can be attained after 10,000 hours of study. I have often wondered if that idea applied to language learning.
