No, if you are a rational person you should be in the best position to evaluate how well you play. Everyone else evaluates how well you play based on either a very small sample size of hands, or an outdated sample size of hands, or based on what they have read/heard/hype, or how big of a game you talk. If you always played against the same opps or with the same partner and those people were as good or better than you, then their evaluation would might be more accurate than yours. But even then there are hands you play right where you know you thought about it wrongly and got lucky or something, and only you know that.
