Definitely not.

On the contrary, they must embrace credit cards with both hands.

At least I did when I was “younger generation”, and I count that as one of the best personal finance management decisions I’ve made in my life.

I’ve written a number of comprehensive answers on the advantages of credit card. You can find them at https://www.quora.com/search?q=credit%20card&author=87429.

Here’s a quick tl;dr version:

  1. Backup if you suddenly run out of cash or are faced with an emergency expense
  2. Rewards
  3. Build credit history

The only advice I’ll give for managing credit card is: MANAGE CREDIT CARD.

In other words, don’t let credit card manage you.

Avoid debt as far as possible. Pay off your monthly balance in full every month, otherwise interest and financing costs could prove exorbitant and you could fall into a debt trap.
