The corporate job is worthwhile, in spite of the shrewd managers and office politics only if:
1) It's in an industry where you can learn the business, and it's your long term goal to start a similar business (with the end goal of piling up massive wealth). You are an apprentice there, an intern.
2) You are using the job to afford food on your plate and roof on your head, and have a clear exit plan (6 months / 1 year max). And are able to save enough money to start your business with the bare minimum.
Do not get addicted to the fixed salary and warmth of the office culture. Your colleagues are like temporary side chicks who you plan to dump when the time comes. Eat, drink, joke, play with them but do not get too attached to them. You are like a secret agent who's there to suck the info and experience you need for a bigger goal of your own self interest.
"The kingdom is rich and bountiful, so you'll eat, drink and be merry. But you'll never be King. If you want more adventure, you've gotta get on your horse and ride out of the kingdom when the time comes and find your own dragon to slay." - (don't know who wrote this but I have it in my Google keep notes).
