1. You only get paid when you're working.
Aren't you brought up brainwashed thinking it's reasonable and intelligent to only earn while you put in the hard yards? All successful people, no exceptions, build their furtunes by creating something that makes money for them 24/7. Don't mule yourself into the dirt working for something that doesn't pay while you sleep. Remember, if you don't follow your dreams, someone else will hire ya to build their own.
2. Finite experience.
Problem with getting experience from a job is that you usually just repeat the same limited experience over and over. You learn a lot in the beginning and then stagnate. Why waste your limited youth doing something that won't produce nothing for your deserving lazy future.
3. Slavery isn't dead.
Start recognizing it. Humans are not meant to be raised in cages (offices as you call it). You must have some talent that makes you special, use it. Don't be a cog in a monstrous machine. Is there any spark of free will left inside you? Or has your conditioning made you a pet for life? Be creative. Be your own boss.
4. Just too many mouths to feed.
Employee income is the most heavily taxed there is, almost half of what you make. It's for you that abbreviations like CTC (cost to the company) have been derived, to make you feel wealthy, though you'll never see that beefy amount credited into your bank account.
5. Way too risky.
Most believe getting a job is safest and most secured way to support their career. That's hilarious. Does putting yourself in a position where someone else can turn off all your income just by saying two words (“You’re fired”) sound like a safe and secure situation to you? Does having only one income stream honestly sound more secure than having 5?
6. It's a free world. Be free.
If you run into an idiot in the entrepreneurial world, you can turn around and head the other way. Start something fresh, smarter. When you run into an idiot in the corporate world, you have to turn around and say, “Sorry, boss.”
7. Define your own hours.
Who says you can be productive only between 10am to 5pm? Human brains never sleep, and hence you can have that problem solving idea anytime. Work when you're in your top form.
8. Don't suffer a for stupid team.
You don't chose who works with you, your boss does, then why you've to pay for the mistakes that Mr X and Miss Y did? Do your own thing, chose your own team and see the difference.
