<prompt> Human: To extrapolate on the title a bit:As a young, urban professional meaning no car, family, or business expenses who travels only for vacation, I dont have any recurring large-scale costs to worry about besides rent.However, I have been considering opening a credit card to accumulate rewards for vacation travel and to build credit. Does it makes sense to use such a card for regular expenses and then pay off the full balance immediately each month?If you have any recos for what cards are good for this Id be happy to take them! Currently trolling around on for ideas.  <response>: As long as you pay in full every month. Thats how most people use credit cards.
