unmotivated
Not feeling like doing things you know you should do.
Unmotivated describes someone who lacks the energy, desire, or drive to do something. When you feel unmotivated, you know what you should do (finish your homework, practice piano, clean your room), but you can't seem to make yourself care enough to start.
Everyone feels unmotivated sometimes. Maybe you're tired, or the task seems boring, or you don't see the point. A student might feel unmotivated to study vocabulary words that seem useless, or unmotivated to practice free throws after missing twenty in a row.
The word can describe a temporary feeling or a longer pattern. You might wake up feeling unmotivated on a rainy Monday morning, but by lunchtime your energy returns. But someone who consistently lacks motivation might struggle to complete projects or pursue goals, even ones they claim to care about.
Unmotivated is different from lazy. Lazy suggests someone avoids work they could easily do. Unmotivated means the inner spark that usually drives you forward has dimmed, temporarily or for a longer time. Sometimes finding that motivation again means breaking a big task into smaller pieces, or remembering why something matters to you in the first place.
