Now that you have your hardware and software all set up, it is time to… get educated. The easiest way to understand all the clockwork behind the pretty graphical interfaces and how to use it correctly, is to invest at least a couple of days into tutorials and demos. Fortunately, there are dozens of these available online for free, regardless of which DAW you picked. The sooner you start researching and taking in all the tips and tricks, the closer you will get to actually producing something.
Once you start feeling like you have a basic grip on the software, you should immediately start creating songs. Do not worry if your first ten (or hundred) tracks are not even worth playing to friends, let alone uploading online. All great musicians started by trial and error, so be patient and prepare yourself for a lot of practice and many failures, until it all eventually starts coming together. Your best bet is to begin by putting together songs from loops, which are repeating short sections of tracks. There are hundreds of websites where you can download royalty-free loops for your musical experiments.
In parallel with creating your first songs, you also need to gain, or to brush up, your knowledge of the basics of musical theory and sound design. While this seems a bit boring, it will help you have a better understanding of what you are doing, and it will protect you from many beginner’s mistakes. If you do not like reading, you will be happy to know that there are thousands of YouTube tutorials that can teach you these basics in a couple of hours. Once you know more about genres, song structure, audio synthesis, mixing and mastering, your approach to music production will improve greatly.

As a conclusion, if you are passionate about music and attracted by music production, do not let anything stop you from trying. It doesn’t cost much, except for your time and maybe a small cash investment, but it is certainly an exciting experience and a chance to discover your talents and get to know yourself better. Good luck!
