I've had friends in the past who tried to influence or some trap me through investments or gambling, but after experiencing it a few times, I haven't done it again. If someone persistently tells me they have a plan, or even if it's a sports bet, I don't care. If I'm going to do something I want, I prefer to take the risk, not based on someone else's opinion.
We decline because we have already experienced it. But what happens to those who have not experienced it? Most likely, they get tempted and fall into the trap.
We have to be wiser when it comes to investing because not all investments offer earning opportunities. Some of them are garbage. That is why we should think more deeply, take the time to think, and avoid rash decisions.
If that happens to me, I will tell that person that I have to research it and make a decision later. And also to tell him not to expect approval as well.
