Execution is ambition translated into observable behavior.

Ambition that stays internal cannot be distinguished from daydreaming, including by you. Execution is what makes it observable, first to others and more importantly to yourself, since behaviour is the only reliable evidence of what you actually intend. Feelings about a goal are cheap.

Look at your last week and ask what someone could infer about your ambitions from your behaviour alone. Where that differs from what you would claim, the behaviour is the accurate account.
