Opportunity is only for well prepared

to prepare ... prepared = adjective

In my country we have this quote “Opportunity is only for the well prepared”.

MIt means if you are not ready, even when opportunity arises, you still end up with nothing.

I used to believe that.

I use = I use a knife to cut bread
I used to live in a large city. = I don't live in a large city any more. I live in a small village now.
"I used to + verb" = I don't do that any more.

But now I begin question what is an ing the meaning of "opportunity means"?

Example: When I present an idea to an investor, they accepted it and I make a fortune from this idea.

all verbs in present tense

How about I just convince someone to listen to me, I get what I want, and they get what they want.

That is much more simpler and easyier to understand.

Don't need both adjectives "simpler, easier" - says the same thing twice

So, anybody, anywhere and at any time willcan be my moment of opportunity moment.

How can I convince successfully ibecome successful is all the matters.¶
How can I successfully convince people - that's all theat matters.
