I use Dan Passarelli from MarketTaker and Todd Horwitz. Not a big fan of tasty. Too much personality worship
Here's something to think about. If you sell a put on MSFT and AAPL and the market tanks, do you loose on both positions? If I die, does that mean you die? If my house blows up, does your house blow up? What about the premium you collected from MSFT and AAPL puts? Can you invest in land development with those premiums?
All of the above applies, of course. The main reason why selling vol is different from providing insurance is the lack of barriers to entry. It's very hard to open an insurance company but it's pretty easy to open a TastyTrade account.
There is an important exception to that rule - going to work for someone, i.e. "an apprenticeship". Most people who make money in the market have learned this way and then extended what they learned via their own experience.
