What i've once read and find good practice is the following:
Try to make a beat from scratch to final beat in 1 hour.
It has to have at least 2 layered samples, a full beat in some sequences and a bassline. The value of this technique is that you are forcing yourself to make creative decisions in a fixed time limit. So no lingering around in this hour (set a timer to push yourself!) and keep it progressing. When time is up youre ready to go and record the song live into a daw. Next!
After a while you"ll have a stack of hiphop instrumentals in your playlist for ideas or youre own listening pleasure
Now and then i do this and im loving it because normally i take my time for this shit because quality over quantity indeed!
