There are opportunities everywhere if you know how to look.
How to look can be learned through hard experience, practical knowledge, or even can be gained through book learning.
What to look for can be learned through hard experience, gaining a qualification or a credential, or through hard work.
Where to look for an opportunity can be learned through hard knocks, formalized education, or just good old-fashioned gut intuition.
But the courage to act on what you are looking at, the courage to take a risk to engage, implement, and activate on an idea; that, courage has nothing to do with external opportunities.
That courage comes from who you are on the inside.
The biggest opportunities you can ever leverage lie inside yourself.
