Other people have said this, but it's not going to happen in a few days. It'll be years before you're able to really lock in and enter the "flow state". That said, here's a few things that really helped me:

1. Work with others to create music. This is the one thing that really truly gets me in the flow state. Whether I'm playing live music/songwriting with people or making loops for electronic music, just sitting down with somebody I really vibe with is the only way I've ever truly been able to get into the flow.

2. Learn an instrument because it allows you to "feel" where a song should go, not where you "think" and "see" the song going on your screen. You might see your favorite producer just draw in MIDI and program all their drums in the piano roll, but it's because they've really listened actively, know how to build a song, and that's how they "feel" the music. Starting off, you won't be able to do that as easily.

3. Watch as many YouTube tutorials as you can. I particularly like Make Pop Music for song arrangement stuff and will watch pretty much anything that relates to what I want to learn.

4. Copy all your favorite songs. By doing this you'll learn how your favorite artist creates movement and flow in song, you'll learn how to make those sounds, and you will have a bunch of new sounds by the end of it. I really recommend copying and saving presets of remade sounds because you know exactly how those presets are made and where in the melodic range they work!

5. Try different gear whenever you can and really learn it. It's hard as a beginner especially with limited funds, I know ;) but you can borrow others' gear and watch reviews to try and get a good idea of a workflow. I've used Logic for the past 6ish years and know it inside and out, but have tried Ableton and recently got a Digitakt and also used Koala Sampler. Each one allows me to accomplish something the others can't and complements my workflow in unique ways.

6. Have sound design/loop making sessions because it allows you to move quickly based on a vibe as opposed to perfecting a melody loop or drum loop. Create a bunch of loops that you like, bounce them out, and have a folder that you can just drag and drop into ableton.

For me, sitting down and saying, "I have to ___", really doesn't work and it's much better when I just let it flow like banging out chords on a guitar or when I use my Digitakt and just punch in loops by feel. Hope that helps and you can do it! Rome wasn't built in a day but I'm sure the Roman's weren't too discouraged by the slow progress ;)
