Pull a joni mitchell and engage in arts that differ from your primary to inform it at a later time.
If you lean more toward visual arts try poetry, song writing, music making, acting/performances for the self, crochet, clay, claymation, videography, sound collection, whistling, discovering new sounds you can make etc.
Often when i want to create but i feel tired or uninspired i try to use still life or my surroundings— BUT If thats boring i ask myself a question and let my train of thought ramble -> connecting that rambling to my pen on paper
Honestly setting your inner critic to rest and creating things that are imperfect is actually incredible!
More often than not letting first drafts be final for a moment allows you to discover what you crave to create.
