Have you ever noticed a plane taking off.. it keeps moving around for a while till the runaway is clear; and once the runaway is clear it puts the entire energy and thrust in that one run and within few seconds the plane lifts of the ground. If it were to not exert that visible energy there is no way it would take off the ground. Our lives are similar unless we put all our passion and energy to something, we will keep hovering around and never take off.

So what are you conserving the energies for, time is now... take off.
