3. Comparative Analysis

• ～たら (〜tara): This can also express conditional scenarios, but is less strict about the sequence of actions compared to ～てからでないと. For example, "食べたら行きます" (tabetara ikimasu - "If I eat, I will go") does not imply that you must eat first without fail.
• ～ていないと (〜te inai to): This indicates that if something has not happened (e.g., "寝ていないと"), it might prevent another action from occurring, but it doesn't focus explicitly on the sequence of actions as much as ～てからでないと.
