Look inward and you'll see what needs to change for yourself. Keep looking inward and you won't know what change could potentially look like.
You'll miss out on seeing yourself reflected in the change of others.
Look outward and you'll see how everyone else is changing. Keep looking outward and you'll only see what is changing around you.
You'll miss out on seeing others reflected in the change you might create.
Balance here is key, both in the looking inside to seek the change you desire then in the reflecting oneself onto others to size, measure and course correct the change that you desire.
Inward and outward. Without fear or favour. Contemplatiion then action.
