Hi.
I agree with Derbeno : practice. Even 10 minutes a day, if you can't more. But practice. On your drums, on the table, on the steering wheel when the traffic light is red, on your laps when you wait for the bus, on the work surface in the kitchen when you're cooking and waiting for the water to boil, practice everywhere and everytime. I'm not the first one to say that, and I won't be the last one either.
This being said : be aware you won't replace Giovanni - and neither shall I - unless you're very young, (which is not my case...) and practice hard and steadily.
But once you've learned some Giovanni's links (or Angá's, or Tata Güiness', Changuito's, etc.), be yourself, and play... like yourself. I know I shall never play like these masters, but I'd like to reach the point where listeners could recognize my playing without seeing me. This would be a real progress to me (assuming my playing is good, of course...
)
Don't give up and keep practicing. And check out the links burke gave you.
Just my 2 cents.
