The key is to set goals. There are many free how-to tutorials here at CiC and elsewhere. Pick a topic that you are interested in and find out all you can about it. Then shoot to improve your skill at that particular goal.
The sole goal 'taking thousands of pictures' will not help you to improve. There must be a purpose for the pictures you shoot if you want to improve. It may take well over a thousand purposeful pictures but by setting goals and working to achieve them for learning camera technique, post processing skills, and perhaps most importantly the basics of composition, you will steadily improve.
If you want to improve, set a goal, shoot, evaluate the results, get constructive feedback, make changes to your technique and fine -tune your goals and reshoot to improve the result. Repeat this until you have reached a level of satisfaction you are currently happy with and move on to a new goal.
