Exercising power from a place of strength is virtue, and contrary when power is saught after to fill a void it originates from a lack or weakness. That lack is either rooted in the heart or mind, and one gain is at the expense of the other.

For example, your own reasoning can utelise or feed off fear to suppress or avoid expressions of unregulated emotions, and the backlash is usually guilt or resentment. Likewise, a lack of confidence may feed off the rationale of the ego to avoid confrontations by a fake sense of control, and the backlash is usually shame or a lowered self esteem.

We need to align our behaviour and cognition to make it easier to realize our intended goals when excersing our power. Seeking power for the sake of power feeds our ego, no matter how powerful we may seem, if it originates from a lack it will need to feed on the weak and is only powerful in that said contrast.

Weakness has no virtue, choosing when to excersise power takes strength, choosing how to excersise power takes courage, and choosing who to excersise power on takes humility and modesty.

Gaining power is an endeavour, wanting it is not wrong, but in order for it to be balanced it needs to draw from feelings, emotions and imagination as much as observation, analysis and logic. It takes both control and a restrain of impulses to be able to do something powerful, in other words, most of our bad habits are due to a lack of willpower.
