Why do traders ignore good advice

So really, this is going to a short vent post. And to be clear, this isn't a rant about people ignoring my advice, that's fine, I don't really care it's their money.

As alot of you would know I regularly post on the whirlpool forum (www.whirlpool.net.au) and that forum as a great sub-forum on Finance. 

The finance forum is great melting pot of many different ideas, thoughts and people. There have been a number of ongoing discussion about trading, investing, crypto etc. I've been reading and participating in the forums for a while.

However, what I'm seeing now is that lots of traders write off the current market with quip, it's different this time. In reality its really not. 

Lots of those offering advice have usually been through the pain and know that really the markets never really change.

In summary, ignore advice at your own peril :-)
