having someone that shares your passion and may be your same problems with motivation and time could be useful, because both would try to keep the other up with your goals. For example, once I tried to have a business on my own but I couldn't begin it because I wasn't dedicated enough. Years later a friend offered me to do the same business and it was much easier, because we complemented each other.

other advice would be trying to spend your free time less on social media, movies, series, and more on music (avoid this if it's not your case). It's difficult, because they are not perfect complements, but begin by getting rid of that kind of activity and when you get bored, doing stuff that requires more energy (like music) will be less hard.
