Hate to sound like a quote from a movie, but that just means it's not personal to you. And you're still focusing on the OP's errors while pushing your point across, and ignoring the initial problem.
SO, what's your answer to his gripe?
And, since the OP is from Trinidad and Tobago (take the time to click once on his "Facebook" link and you can see that) where the English has a local 'twist' - what you and I call English differs from his version - I don't see that any of the complaints are valid at all.
Yes, he'll have to work 10x harder if he wants to "make it" in the USA, but that's up to him.
We can push in the right direction, but he's only young and distancing oneself emotionally takes time, maturity and a certain amount of failure.
Relatively new learning photography? Yes, he has a long way to go. Relatively new learning business? No, he needs to worry about it now.
True indeed. I don't bash someone who's native language isn't English, but if they're communicating in that language, they usually apologize so the other person "gets it."
I think the best advice so far is simply to "not worry" about anyone who thinks $40 is expensive.
