Let me translate a bit what you're saying. It's right now what I hear or read between the lines or rather what I want to read because such introductions as yours are somewhat annoying and tbh quite worthless.
I was introduced to this forum through one of my friends.
Possibly: I'm too dumb to find it myself because I've no focus and goals.
I have heard that there are plenty of free opportunities for learning and earning by making appropriate use of this forum without any investment.
Where's the free lunch? Can someone bring it to me, maybe spoon feed me, too?
What should I remember as a newcomer and where should I begin?
Definitely, spoon feed me, pleeeease, now!
Are you sure you want to embarrass yourself any more? Surprise me, seriously!
