I have 3 under my belt. Follow the directions in your kit and you will have a tasty brew.
The first time can be a little chaotic just trying to understand the process. After that, it gets easier. As others have said, sanitize, be patient, follow the directions, and be patient. You will want to taste it, take gravity readings, etc way too early. Let it do it's thing and leave it alone. Your tastebuds will thank you.
I also found that taking notes helps. Keep a log and include dates and times. I also make a note when opening a bottle if it's been a while.
After the first, the second and so on get easier. I have been reading the books I bought a second time because much more of it makes sense.
Have fun!
