There is no obstacle that I cannot overcome.

Overcome doesn't only mean through.

Some things get gone around. Some get outlasted — you are simply still there in March, and the thing that looked immovable in November has moved for reasons entirely of its own. Some turn out to have a door on the far side that nobody thought to mention.

The evidence is behind you and it is unglamorous. Make a short inventory of the situations you were certain you would not survive. You did not handle a single one of them well. You handled them.

That is the only track record anybody has, and it is better than it feels from inside.
