It led me to "STEAL LIKE AN ARTIST" and tips like "choose a subject", "choose someone to mirror", but MOSTLY important: "don't feel like drawing? draw at least a line, and then if you feel like, you will keep drawing". I even apply this last piece of advice to work: "don't feel like programming? write just one line of code". Naturally that lead to another line (code or drawing) and another and another.. and then you finish something daily.
Here is my suggestion to you, it has to do with how to structure your study time. Think "study and apply". I have no idea what level you are at, because you haven't shared any of your drawings, so it's hard to know what to suggest subject-wise, but start with a subject you want to study and go to just one source for that subject for the moment. For example, if you want to learn about perspective, pick one place to study it at this time.
Start with the first principle they teach you. After you've listened to or read the information for that first principle and have taken notes, do a few very basic practice sketches. If it's one point perspective, draw a horizon line and 5-10 boxes. Maybe you find a cool piece of art that uses one point perspective (do not spend hours looking for this), and you trace all the receding lines of this piece to the horizon. Maybe you do a simplified line drawing of this cool piece of art. This counts as the "study" portion of "study and apply". Still not getting the principle of one point perspective? Now would be an ok time to look at a different source, but be strategic. You are only searching for answers on one point perspective. Don't get ahead of yourself. Now apply the information in a finished piece. Now, does this finished piece mean, fully rendered, full value, full color masterpiece? No. This means something as simple as a line drawing of a hallway with doors and windows in perspective. Maybe you do another "finished piece" for this particular subject, maybe you don't. This might take up your whole study session of 1-3 hours. This might take as little as 15 minutes, depending on how long the lecture is or how easily it comes to you.
Move on to the next principle, say 2 point perspective. Listen or read the principles of 2 point perspective. Do a few sketches of boxes in 2 point (study).Then "apply" by doing a very simple house or city scene without much detail.
After you've gone through a good amount of the principles from your source material, (2 point perspective, drawing circles in perspective, measuring distances, scaling things in perspective, etc) do a larger more detailed piece. Maybe you do another city scene but add more details like windows and doors, maybe a few trees. Maybe you draw from life. Look at your couch and draw your couch using the details from life, but applying the principles you've learned in perspective.
You can have a few subjects going at a time, but separate them in your sessions at first.
Remember that you can always come back to a subject. Often times it is just not possible to absorb all the information at one time. You need a rest period from the subject matter and you will pick up things the next time around.
Here are examples from my own perspective study. Here are some of the copies I made. Some of these may seem complex, but I also did just basic boxes in perspective that I didn't bother to save. I would consider this the study part of "study and apply"
Here are examples of my "apply" or "finished pieces". They could also be considered just studies, but they are really applying the principles learned in a more engaged way that helps the material stick better. 
Again, not sure where you are as far as skills go. But a good place to start, at least here at svs would be, Drawing Fundamentals, How to Draw Everything, Visualizing Drawing in Perspective, and Mastering Perspective. Start somewhere. Pick one. Do any of the exercises recommended or included in the course. Start with one and practice before you move on to something else. I would focus on some fundamentals before pressuring yourself to compose a personal piece. Think of your art right now as study. It makes it less personal.
