When I first started working, I was among the few guys who resisted the temptation of getting a credit card. After seeing some of my colleagues falling into the credit card debt trap, I was convinced that I had made the right choice and continued to pay for stuff and services by cash or cheque. However, that changed when I started traveling quite a bit and had to stay in hotels.
Carrying around a lot of cash was not a very good idea and a lot of places didn't accept cheques. Moreover I discovered that I needed a card to book flights and hotel rooms. In the end I gave in. I signed up for a credit card. Only then did I realise how convenient it was. Now I could shop online, buy the big stuff I had always wanted and pay it off in installments. I never had to be worried about how much I had in my pocket when I was entertaining friends and family. My opinion of credit cards have definitely changed. The loyalty rewards are a nice extra. So far I have claimed watches and bags. I really like the fact that unlike some other companies, the reward points on my cards never expire.
Anyway, does that make you want to get a credit card? Just make sure that you don't over spend and pay off as much as you can every month.
