I recently started working.
Before I had all day to practice my English and still had time.
But now I do not know what to do to continue learning as I go to work at 5 o’clock in the morning and come home the 20 hours.
I definitely need your advice.
You did so well in a very short time. What was it that let you progress? It wasn’t just time! With your kind of motivation you’ll find ways of filling in the empty times throughout the day. Even if it is only 5 minutes here and 5 minutes there, do the things in English that are most important to you. When you are used to your working day, you’ll find a pattern which will work for you. Good luck!
And even if you concentrate on your work during the day and cannot justify spending 5 minutes here and 5 minutes there on learning English during your working day, you still have the time on your way to work and on your way home. If it transpires that too is impossible, you can spend 30 minutes at home everyday in the evenings on your English. You can use it as a means to lull you to sleep at night 
Not to mention the weekends too or whatever days you have off. It is possible to remain dedicated to learning languages even if you never go near the language during your working day.
Hi, Lucas!
Do you go to your work by car, bus or subway? Enjoy your travel listening some podcast in English in your MP3 player. You can either enjoy your break to the lunch to practice any listening and reading, too. I use these resources to always still connected with English. And it’s a good method for enjoy the time while I’m in traffic (I live in São Paulo, where we have serious problems with traffic).
If you need some help, let me help you.
