Opportunity is missed by most because it is dressed in overalls and looks like work.

Chances rarely announce themselves as chances. They show up as an unglamorous task, an assignment nobody wanted, a problem that is tedious and has been left alone for years, and they get passed over because they look exactly like more work. The people who benefit are often just the ones who took the dull thing seriously.

Have a look at what is being avoided around you: the process nobody will own, the customer nobody calls back, the part of your field everyone finds boring. Doing one of those properly is a slow and reliable way to become the person who is asked next time.
