Fly,fly, fly and fly.
Fly when you wake up in the morning, fly another sortie before going to work. Fly at lunch, fly for an hour when you get home from work. Instead of going to sleep at 10, fly for 2 hours. Then get up at 5 and do it again! Weekends you should spend at least 8 hours a day beind the stick.
Also fly smart, diving into the first furball you see never made anyone a good stick. Pick fights you have a chance of winning, where you hold at least 1 advantage. This can be taken to extreme however.
