I don't think the lesson is enough, because theory is always different from the actual market situation. yes, you have to walk together between lessons and hands-on practice. in all fields, whether it's work, business or investment, all require direct learning and practice in the field.
Learning is not only the process of getting clear theoretical information. When you do certain actions you look what is working what - not, what works better, so in simple words - you gain experience what is the part of learning.
But nobody will argue with the fact that the more you learn the better. I didn't saw people here who was uncomfortable because they knew more than others
