DislikedThat the learning curve will be shortened because you are really really smart and determined. That if you trade 15 hours a day for a year, you'll have the same experience as somebody who has traded one hour a day for 15 years.Ignored
So, where is the breakeven point? Is trading three hours a day ok? Will that still be attributed to three 'full' hours and thus you only have to do that for 5 years? Where do the hours spent trading become 'wasted'?
I'd guess that anywhere from 1-6 hours are probably helpful for most people, but after that the attention and retention start to fade and you probably need a day to rest/reset and get yourself ready to re-absorb new experiences from another day of trading/researching.
In any case, people are so different, it is only a vague gauge and will also be dependent upon many other factors, such as their environment, available resources, mentors, etc.
* Being being really really smart can be a down-side, as you might be a person that overthinks the process and detail and gets lost amid the various indicators, news items, fundamental issues, etc.
* Determined - pretty much a useful trait, unless there is so much and the person is actually headstrong/bullheaded/stubborn. (So, in moderation as with most things)
