Credit cards are, for the vast majority that use them, a terrible idea. People end up paying thousands for things that cost them a hundred bucks all for the convenience of owning shit you actually cant afford.
Like you said, there are some rare people such as yourself that use them properly. It is pretty rare though. I know so many people that dug that hole deeper and deeper and deeper and they have nothing to show for it.
I have owned exactly one credit card in my lifetime, been forced to carry another for work and I can say I will never own one again. I think my total credit card expenditures come out to about 100 bucks and I paid that immediately.
I just do not see the value in my own circumstance that a credit card would bring.
