As much as I love inspiration sites for design, I got lost in them very quickly especially early in my career. I didn't accomplish much, and had hundreds of tabs open on my laptop. I'd recommend getting outside and searching for experiences that need help. A former Product Manager at Microsoft told me that she wanted to find a way to digitally distribute MS Office after going on vacation and seeing hundreds of boxes of her software stacked in a university bookstore. She would have never gotten the inspiration had she not left her desk! Go explore in real life!
