If you want to, you can force yourself to work.
If you write something "bad", you can often write something to fit the "bad" thing and it will likely sound better. Then you can proceed to delete the bad thing, should you desire.
Using loops/whatever and deleting them afterwards can also work, if you'd like!
Just a tip I rarely see given, but has generally worked for me.
If you'd like to make a lot of music without creative blocks, I feel like you'll probably want to try to learn some sort of "pattern" to let you start off songs quickly. I can't really say I have any tips for formulas you can follow to make songs easier, though. I don't really have any myself.
I guess using reference tracks and putting them into your daw can help too. Just try to be careful that your song isn't too similar to the original... Ideally.
