The hardest step, as always is the first one.
Once you start on it though, the drive and momentum to get things done grows with every passing task completed.
I’m not sure about everyone else, but personally, I feel burdened and drained when I know there are too many things to be done. Ticking them off my list, gives me a sense of accomplishment and energy to get onto the next one. Otherwise, I slump in a puddle of ineptitude and sloth.
