Learn to be patient if profits haven't come today and keep trying to look for opportunities to make profits. That's what I've learned over the years and not just this week because I know that market conditions will always change and I often make mistakes in my analysis which causes me not to be able to get a good time to enter the market. And this makes me have to be patient, waiting for the time to buy or sell but I don't give up because that's the process. As long as we enjoy going through the process, we can survive and benefit.
