World is never easy la ....... in WW1 and WW2 all the front liners who try to win a battle die, you think they got any chance to succeed if they chicken out like you? Sacrifice had to be made in an attempt to have that possibility of winning.

Also if everyone is kept with the mind set of "Oh I'll just keep working for a boss only no need to worry about anything else" you will then never learn or improve your salary will never go up.

Part of working is to understand how a business work and able to share boss problems, when you are very good at it those are no longer problems those became challenge. One day when your boss want to retire or when you are old and experience enough a boss would hope you carry that banner and become your own boss.

Company that hope you become worker forever are not worth staying, because they are not letting you grow.

What I sense in your advice is "gain more experience" before consider venturing into business especially if its a totally unrelated field. Don't rush and butt head a wall you don't know what its made out of"

But instead your list of words make it sound like "Don't ever be a boss".
