New young investor looking for tips/advice!

[Justin Daniel Page]

Hey guys, My name is Justin Page and I am a senior in college. Recently, I read Brandon Turner's book on rental property investing. I can't get enough of it!!! I am on zillow daily, looking at properties, running calculations. I know I am very young in this industry, but I am excited the opportunities it could present in the future. I do have one major question to start this discussion- If you could tell your 21 year old self something to do, regarding real estate investing, what would it be? I look forward to your answers!
