сколь тернист этот путь busin.

[Daffodil3]

Проверьте пож-та перевод предложения:
Те же, кто хоть как-то связан с бизнесом, знают, сколь тернист этот путь (имеется ввиду получение стартового капитала).

Мой вариант:
And those people who are somehow involved in business activities know well what a long and thorny way it is.

[delta]

those people who are in one way or another involved in business know how thorny the path is

[Baxter]

Those who know anything about business are well aware that this way is hedged up with thorns.

[les-nick]

Every rose has its thorn
Like every night has its dawn
Just like every businessman sings his sad, sad song
Every rose has its thorn
