When you try to understand the relatively uncommon, often misunderstood experience of inspiration, your best reference point is the nearly universal, well-explored experience of love.
Since roughly half of all rock songs are about love, our universal jukebox has collected a great deal of wisdom on the subject. When you have a question about inspiration, for example, "Why is it so hard to find inspiration?" just change the word "inspiration" to "love": "Why is it so hard to find love?" Then you're ready to take your question to the jukebox. When an answer emerges, just translate the word "love" back to "inspiration."
This jukebox trick won't necessarily give you a clear answer to your question, but you'll at least get a clearer idea of what the question means.
Perhaps you've been "looking for inspiration/ in all the wrong places." We all know "inspiration takes time/ and it's hard to find." Maybe searching is pointless, and the best you can do is be prepared for when "inspiration comes walking in."
