From Real Power by Janet O. Hagberg:

True Leaders:

Follow a vision, a purpose, an ideal.

Allow for win-win, not just win-lose.

Empower others, not themselves.

Have balance in life, between work community, and family.

Can be vulnerable and reflective.

Treat women, men, and minorities as equals.

Ask why, not how.

Have a spiritual connection to power within and beyond.

See the bottom line as a means to a larger organizational purpose, not an end in itself.

Live with integrity as their hallmark.

I recommend Hagberg’s book as an interesting and powerful guide to one’s growth as a leader.
