First, start with what you have.
It can be very tempting to go to a music store, ask for recommendations, and spend a lot of money on new gear. Unfortunately, I made this mistake early on, and ten years later I sold several canada business email list things that I never used. There are very few things that are actually necessary to produce music. For example, a laptop, headphones, and some kind of production software.
Start with whatever laptop you have, if it's powerful enough to produce on. You can get a decent pair of headphones for around $100, and production software companies will often offer free trials of their software to get you started. If you want to build from there, you can add an audio interface and microphone to record audio, then a pair of studio monitors to listen to it with something other than headphones.

Find a teacher
I wish I had realized the importance of this point sooner. Many people choose to teach themselves on YouTube, and while it can be an accessible place to start, it can easily take five times longer to learn. Plus, not knowing what you don't know makes it difficult to know what to look for. Taking a few lessons or finding a short course, even if just to learn the basics, can dramatically shorten the learning curve.
Pro Tip: MPW offers a free Introduction to Music Production class that you can sign up for, which is a great starting point for someone just getting started.
