You're way ahead of a lot of people already. You didn't just pick up some old worn out derelict and think "I'm going to fix this boat up and go blue water cruising!"
Your approach is thoughtful and IMO the correct one. Start small, acquire your skills and learn from your mistakes. You'll make a bunch, it's just part of the game. There are some very knowledgeable people on this site that will help and give you some advice. Sadly, one of the most knowledgeable and prolific contributors to this site died in 2018. His name was Paul Ricelli. He was the most helpful person on the planet, offering advice and encouragement to me as I restored my boat years ago. I'll post a link to his website that is thankfully still maintained. My suggestion is to read through it,
all of it. His legacy lives on in thousands of threads on this site. Search this site for information. It's all here, you just need to look.

For now I'll offer this: In order to have a successful build or restoration you'll need a place to work. A small boat can be done in your back yard, larger boats will probably run afoul of your neighbors or the zoning department. While you don't need a building, you'll need a substantial structure that will survive storms and wind. You'll need room to work around your boat and room for tools, staging and materials storage. You'll want a secure area. You'll need power, water, probably heat and a bathroom of some sort nearby. All this needs planning before you even start to build a support frame for your boat. It all costs money.
I'll post one more link to a thread that I started some time ago that documented what it cost to do my restoration of a relatively small cruiser. I'm not trying to scare anyone but you might find it informative.
