no i don't believe you have to walk on other people to be successful, you just have to be good at something that is in demand.
but if you mean success by easy riches i would say you probably have to walk on some people.
every one i hear of that is super rich is ether soulless, or lost their wife/husbands/kids and are just left with a bunch of money and a big empty house.
I'm all for having just enough money, not to much and not to little, but if i have to be poor to enjoy what I'm doing, i can handle it.
rather be poor and happy then rich and miserable.
...maybe i just contradicted my self??
