This quote applies in various contexts. I use it here as it applies, for me, to the core of personal development.
The beginning of "elevating" ourselves starts with a "conscious endeavour" to explore that which is within; who we are, what we are, how we are. Our dreams for ourselves and for our world are in our own hands and we have the choice to reach them, or not. Even not making a choice is a choice.
Mahatma Ghandi said " BE the change you want to see in the world".
How about starting with your own personal world?
Your discoveries will be endless and surprising beyond what you have imagined ...yet.
