There's nothing wrong with having swords for a goal, but like everyone else is saying, you need to start with the basics. A good s hook is in my opinion much more impressive than a really bad sword. If you want to be "good" at anything, you have to do something that others are not doing. If people could just go out and make a sword, than anybody with a DIY mindset would be making them. The thing that others are not doing is practice. That is THE reason that not everybody plays an instrument, not everybody cooks, and not everybody does blacksmithing. It doesn't matter how good of a teacher you have. You have to learn hammer control. You can't just have someone tell you to hold your hammer a certain way and all the sudden you have hammer control down. You have to PRACTICE! Kudos for having the determination to take on such a task. You'll get there if you PRACTICE!
BTW, you can't say "I'm going to use if for chopping through brush" as an excuse for poor heat treating. Once I was using a cheap sword for that very job, and the minute it struck a fairly solid branch, it shattered into tree pieces.
