My biggest piece of advice is don’t worry about too much about becoming a master of everything. It’s said it takes 10,000 hours to become an expert in something. There’s only so many fields you can choose.
I am not saying don’t be ambitious. What I am saying is, do you NEED to make your own music when you can get royalty free music that’s almost as good? Do you NEED everything to be an original model when you can get free assets or cheap assets?
Obviously you need to decide what you need to do yourself, my point is just, don’t be afraid to stick with what works fast and now, until you’re at a point where using the better stuff matters. If that makes sense.
Oh, and youtube youtube youtube. Get a second monitor, screen, or tablet if you can and follow lots of tutorials.
