Obsessing over things

I often find that I will see something new and become so obsessed with it that I am researching it in class , in the morning, at night, and dreaming about it. This happens all the time . I was once obsessed with learning how to make chapstick so I bought packs of chapstick tubes and spent all my time learning how to make them and making them and now I never make any and I just have tubes everywhere . I wanted to learn how to to acrylic nails and so I bought acrylic nail sets and practiced that. Now I really want a pet rat and I have started researching so much about them every single day and I’m thinking about buying them but like what if this is just me obsessing over something for no reason? Do I have a problem ?
