I can share some lesson I learned from the live account.
After the first profitable month I felt the greed which is typical for manual trading. Than I increased the lot traded 3 times and lost in the first week half of the account. I believed that after having one profitable month I can not lose and I will have the same profits next month. Well, it did not happen. I needed another three months to recover.
Money management is all about it, and patience…I believe Guns and Roses wrote the song Patience for the traders :)
