I have lost some amount in trading but I think it’s much better than losing money in gambling or so. I see the loss as the fees for learning something new or say the fees to learn trading lessons so I am not much disappointed while trading. Trading is a science as well as an art and the commerce is just a medium to deal with it so I always prepare for the worst and hope for the best.
Some people would say that it's okay to lose their money from gambling and say that it's a learning experience, too. 
People see what they want to see even if it means they're going to lose money. It's okay to consider those as "fee" for learning something if it's not that much. Otherwise, I think it would be much better if you buy a paid e-book out there. Find what's the best e-book about trading and you surely will learn much more than you can from losing money from trading. But I guess losing some money from trading is just a normal thing and it's experienced even by the excellent traders out there.If I want to fight a war, I would take the sword and start practicing with it. Yes, initially it is better to learn from experts but on the next stage, one must go with actual experience of doing something and I always prefer to ‘regret of doing something’ instead of ‘regret of not doing something’.
