Alright, that's good advice.
So, do you think one/two markets and trade them exclusively, or, one/two and load the boat out of the gate?
I started trading in college in the early 70's (mostly hogs, cows and bellies). My cousin married a commodity broker and the rest is history. I was a retail AE for 12 years ('75-'87).
I think, like your lady said, we have all of the experience and knowledge we need to succeed, we just have to get ourselves under control. I become a gunslinger when I get hot and trade my six shooter in for something in full auto, lol.
I like a good base on a long term chart. An example is uso, (although oil is hard to work with because of the politics. More stress). This is not one I would choose but is an example of the type of trade set-up. The problem is the time draining capital when it is just sitting.
I know I am not a good trader. Whatever method I choose cannot appeal to that mindset.
I think swinging for the fence is fine if done right. Has worked for me at times. In fact, that is essentially what we are trying to do. I don't buy an option unless I think it is a potential 10X.
