Welcome @Conner Sweet! Super excited to see a young man like yourself pursuing skills to achieve financial goals and freedom and not relying on a paycheck from others. You will learn so much about business, capitalism, taxation, what is wrong with our country, meet many different types of people, your own flaws and strengths and the list goes on! There is nothing like this! (I'm a retired homeschool mom so you can see my excitement in your eagerness to take this step at such a young age!)
My biggest advice is that this is more a people business than a knowledge business. The knowledge will come. Keep making connections in every direction. Hold true to integrity and treat people right and you will have a great business. Be stingy, greedy and rude and you will have few friends, few recommendations and lose out on good money.
Get yourself a mentor and go follow him/her around. Offer to work for them for free for a while and you won't regret it! Good luck and keep us posted as to how your getting along!
