What advice do you wish someone had told you at 21 years old?

[Tyler Labrador]

Doesn't have to be real estate related! I just want to hear what life's big lessons have taught you, and how I can learn from it. 

Some of my background:

• I live in Las Vegas, NV
• I have a girlfriend
• I read a lot and I try to go to as many RE events as my schedule allows to network
• I currently save 25% of my income ($500/mo), and next year I plan to cut down on food, rent, and car ( I've heard about the book "Set for Life" and I'm planning on reading it soon! ) in order to save close to 50% after my promotion ($1500/mo)
• No debt, $500 emergency fund. I want to build it to 5k.
• 750 credit score, never missed a payment
• I'm thinking about buying a 4b house next year, living in one bedroom and renting out the other rooms to friends at $500 each. However, Vegas market prices are high and I'm hearing some local investors say that we're starting to enter a recession. Some thoughts?

My goal is financial independence and real estate is my ticket to wealth. Buy and holds will be my bread and butter, and I eventually want to move into multifamily. Any and all advice is appreciated! It doesn't have to be real estate related! Thank you!  (:
