'To get used to' - You get your first job: When you get your first job, you have to get used to a strict timetable because it's quite important don't be late at work. Also, you're getting used to receive several orders from your boss and give your best! - You go on a diet: The most important thing that you have to get used to, it's be regular and know to refuse when people offer you food that you're not allowed to eat. - You have children: I don't have children that I have to look after, but I can imagine some things that the parents have to get used to. First of all could be the care of their children, I mean, you must be thinking all the time about him/her. Another task that you have to get used to, it's when you don't have enough free time for yourself.
