As a biochemist, when I saw "LPS" I thought Lipopolysaccharide. Of course I assume you are referring to littlest pet shop? Do you have an actual pet? If not, I strongly recommend considering it. The unconditional love of a dog (cats can be a little less lovable) is very soul-soothing. Of course dogs require tons more work to take care of, so consider that. Just a thought....Well, my silly motivation is aiming to have a big LPS collection. Maybe that will keep me afloat.
ETA: any small 'motivations' are really beneficial for those of us who struggle to find a reason to carry on in this life. For example, just striving to get to a certain level on a video game has been a thing that I have had to try to look forward to. When it doesn't actually happen, then that can be an issue (aka bummer). But the effort is never wasted.
