Two College Guys Asking for Start Up Tips [I will not promote]

Hello! Me and my college best friend recently graduated from UC Davis with design degrees. We came up with an idea that we believe can go far and bring good to the community if we can bring it to life, but we are completely new to entrepreneurship and start ups. So I was wondering if anyone who has certain experiences can help us with a few foundational and open ended questions to guide us to think, anything would be appreciated: 1. What are the first steps we need to take to transform an idea to a business? 2. Who should we talk to? Where can we go to proceed with the idea? 3. Anything we can do right now to become more ready to actually launch this product when the right time comes? 4. I’ve been listening to podcasts about different entrepreneurs and their stories while reading experiences from Reddit, what else can I do? Both of us believes that creating start ups and growing them to solve problems people face are our true passion Please provide any help, we truly appreciate them!
