Transition from College Life to full time graduate employees

Hello Experienced Blinders, How did you manage a new life as full time professionals in IT/Fintech sector. I was a careless lazy student who barely attended college and passed on the borderline. Now that I've started a full time job, I have to adhere to a strict schedule. Any tips to handle this? TC 8.53 Lpa Location: India YOE: 0 (obviously) #fintech
