Just had GT3 for about two weeks. I can't devote as much time as I would like (wife and 13 month old) but I have been able to get most of the beginner golds and all the easy licenses. Anyway, here is my best advice:
1) Get the endurance license at all costs. Just block off some time and get this done. Then invite family over!
2) (Purists will consider this cheating) .... Pay $5 to nephew, cousin, any youngster who values $5 to race the Super Speedway endurance race. 100 laps, pays $200k and you get great cars.
Here is the scene: It was early on in the game, maybe 10% done, and I had family visit. Two nephews, 10 and 12 yrs old, for three days, and they raced the Speedway (for 3 days!) Seriously it cost me like $50 but it works great. I was able to spend 'quality time' with the family while they packed my bank and garage.
