Bad Financial Advice or worthwhile Credit Card Debt

Hey all, just wanted to first thank this community for everything it has done for me. Came from low income background, had to work multiple jobs in college, and was able to land a EB gig at semi LCOL city. My predicament is that I am currently realizing that I must live out my young life and enjoy the last bits of college/post grad before work starts, however, my financials are in complete shambles. Earlier this year I decided to take out some credit card debt and opened a couple 0 % APR credit cards to fund my lifestyle. Using the cards, I'm going on post-grad and a couple international trips, eating out (nothing crazy), and going out in college. At this point I will have racked up about $20k worth of debt when starting work and I feel as though I am still making a good decision as I would probably regret not doing the things that I have done,. However, I feel like I am at the edge of fucking myself financially. All the cards are 0 % APR for 16 months, so I figured I can just pay these off when working as I wont be traveling or going out, but wanted to get advice from the forum. I truly believe that I would pay 100k+ when im in my 30s to live the life I've been living and go on these trips (spending money to have fun with my friends who are funded by parents) but I know that its getting borderline irresponsible. Feel free to cook ts out of me
