This is very common, during a bull run everyone looks as if they are the best investor in the world as every day they are getting profits and this reinforces that feeling, however we need to be realistic, like most things in our lives your real skills really shine when adversity hits you.

You can clearly see who was just lucky and who is really good when the bad times come to this market, in many cases those that were just riding the good times lose more money than what they earned, while the good traders still make money during the bad times, so do not let those feelings blind you to the truth as more than anyone you know your level of skill and how capable you are.
