there's a lot of ways to do it, stuff like sincere said works...but there's also something that a lot of people don't do...just take a totally new approach to how you make a beat.
for instance (i dunno if you usually start with a certain "part" like i often do but), instead of making sections/loops, just choose 1 thing and go all the way with it...then build everything else from there.
start with your drums...forget making a 4/8 bar part you like...start with your intro, then verse/hook/whatever. then go from there. shyt, do a whole beat of just drums. then go back with a bass or whatever else you're immediately feeling, and play over top of the drums, do the entire track again. and just keep doing the same thing with other elements until it all feels right. think left-to-right instead of working in parts and trying to glue them together.
just an idea.
