I would have to say that airline rewards cards have the best overall rewards when you compare dollar for dollar. Of course, these types of cards are only useful if you enjoy traveling. Then again, who doesn't enjoy traveling!
While airline rewards usually take longer to accrue, a reward for a round trip flight, which these days can easily be $500+, they go far beyond the rewards you may see from a 1-3% cash back rewards card. Now, this is assuming you don't spend gobs of money on your credit card on a monthly basis. If in fact you are spending $50,000 annually on a credit card, then I would have to say that cash back rewards would top my list.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
