Almost everybody, except for a few lucky people, does whatever it takes to make a living, with the limited resources available. It might be having multiple jobs, or washing the clothes while you play with your kid or wathever comes to your mind. 

Personally I try to do so many things at once that sometimes I feel like this sea lion, trying to keep the ball on his nose, while he has to keep his balance on the big one. Nonetheless when you are able to to multiple things your you may experience pure joy :)
