It’s possible to create a life where we only perform tasks when we feel like it.
More likely, though, we end up with commitments. Commitments require us to do work when they feel like it, regardless of whether we do or not.
And the best sorts of commitments create a positive cycle. We end up changing our attitude and our energy precisely because we said we would.
This is one reason why a long vacation can leave us in a torpor. Left to our own devices, we skid to a halt.
