Eventually, what you learn is that you do not have to do it all together, you don't have to get rich tomorrow, you don't have to spend all your money. Spend very little until you are sure you can make a profit, and eventually you will get richer, nobody can get rich in a day, but you can learn to be a great trader on long term and be better.
You have said it all
You dnt have to be overambitious, trying to mk it big at a go, we do learn by ourselves too just matter of patience and care
