<prompt> Human: Im 21, a kitchen worker with a 1300 take home pay a month. My dad was recently diagnosed with stage four throat cancer abour a month and a half ago and is now an hour away staying at the hope lodge while undergoing chemo and radiation for the next month and a half. I make trips up there about twice or three times a week.Also my rent and bills add up to about 700 a month and gas eats up a lot of money, also with food and some travel expenses if I decided to stay the night up with my father. Ive been told my whole life I dont want to get a credit card and also at the opposite end Ive been told to start building credit.So long story short should I open a credit card for my gas and traveling expenses and make payments every month?  <response>: Credit cards are just financial tools. As long as you use them wisely, there is no reason to avoid them like the plague.Just remember to always pay the full statement balance by the statement due date, and youll be fine.
