Work hard now and enjoy later or enjoy now and make memories?

Whats more worth it or what should we do? should we work hard now and sacrifice a trip/party so that we can enjoy in your 40s/50s? If we do this we'll end up not making memories,but if we party now we might make a lot of memories but the life might get hard too in the future? So what's worth it? Securing a future? Or making more memories to look back?
