If believing it make you a tiny bit more motivated...
All right, I've been thinking, when life gives you lemons, don't make lemonade! Make life take the lemons back! Get mad! I don't want your damn lemons! What am I supposed to do with these? Demand to see life's manager!

As much as you can do and as much as you want to do are the same thing. I find this perspective to be very liberating.
No action can be performed without the motivation to initiate it.
Sometimes this relationship is very direct - I want to play video games, therefore I can play video games.
Sometimes it's a bit more obscured. I don't want to fold my laundry, but I do want to be able to find my clothes in my dresser. My desire to find my clothes is greater than my distaste for laundry, therefore, I can fold my laundry.
The language around saying you can't do something is very self-defeating. If I say I can't take care of myself it implies a certain amount of permanency. If I say I don't want to take care of myself, that's temporary and is open to change when I'm feeling better.
More to the point of this meme, thinking that people can help you more than they want to help you is dangerous thinking. The burden of existence sucks, but our fellow humans don't really owe us anything just for existing. They can't help you if they don't want to help you, just like you can't help yourself if you don't want to help yourself.
