You're following the financial industry training right down the line. You should receive a gold star, not criticism. You should keep the approximate number of cards you have now and change them around now and then especially when an special offer appeals to your sense of adventure. As you grow older and your income expands you're supposed to increase the number of cards, the churning of the cards to chase the special offers and of course, increase your level of spending. The financial industry has a very high profit margin, stocks no inventory and has very little brick and motor presence. They need to keep the system moving and your participation at just over the level you can afford will continue to be rewarded with appropriate credit scores and continuing sales contacts and reminders of the need for you to follow instructions. You should be applauded for your participation and especially for recognition early on that this is your place in life and the path toward your happiness. And remember, the offers for new cards will help you to beat the system so pay attention and be prepared to act.
