<prompt> Human: Hello, I am 20 years old. I have a huge future planned for myself as I like to set my goals high. For starters I am dating a girl of 3.5 years and am planning to be engaged within the coming years. I am also planning on entering Pharmacy School and marrying when almost donedone. We will be moving in together, and I have a few questions1. What is the best foolproof way to save money? Obviously not to buy things not needed, but is there anyone here who can pitch into the fact that you should put 20 of your paycheck into your savings etc?2. What is the actual cost of engagementmarrying? Obviously the rings aside and the wedding itself. What financial struggles do most couples fall into?3. I am nervous about having a job while in pharmacy school. But that aside, what considerations should I make to ensure that the costs will be met for an apartmenthouse, etc?  <response>: FYI you want to say I have been dating a girl for 3.5 years. If you say I have been dating a girl of 3.5 years. the police are going to knock on your door.
