I always see myself as a success in all my current and future endeavors

The difference between calling yourself someone trying to get fit and calling yourself a runner shows up at six in the morning, in the dark, in February.

The description is not decoration. It is what gets consulted when the alarm goes, when nobody is watching, and when every available reason to stay in bed is present and reasonable.

How you file yourself governs a hundred small choices before it governs a single large one — which invitations get accepted, whose advice you ask for, whether your hand goes up in the meeting. What gets called success later is mostly assembled out of that filing.
