THIS!
100% true. "everyone has an opinion, even if it's wrong."
It is my money and i am responsible for my actions. If i lose it all. Fine, but at least it was my own decision. Maybe i will learn from it, maybe not, but it is my fault.
Imagine a friend/family member gives you advice and you listen blindly to it and lose a lot of money. This will be awkward the next time you see this person.
There are so many people out with no idea what they talk about or even worse (they know but lie to you to gain some profit).
Most people learn the hard way, but you need to decide on your own. Even parents can be bad counsel.
If someone has to offer advice you can listen, but then check for yourself and then decide.
