I am energetic, enthusiastic, confident, and happy.

Four states, and they rarely clock in on the same morning. Enthusiasm often turns up first and drags the others along behind it. Confidence tends to arrive last, after the thing has already gone well.

They are more linked than they look. Energy is largely made of interest — you can be exhausted at four o'clock and wide awake at half past, because something caught you.

Which suggests the way in is not willing yourself into all four at once. It is finding the single thread that genuinely pulls, and letting it do the recruiting.

Something today will interest you more than the rest. Follow that one further than you normally would.
