Apologies because I'm sure this has been covered in various ways, but I'm trying to decide my best mental approach. I'm naturally intense, but I obviously don't want to be tight. I try to stay calm and focused, but my natural intensity tends to lead me to get frustrated...tight. I know everyone is wired differently. Federer seems very relaxed and Nadal is intense. People say they play their best when they are trying to just have fun, trying to have an Inner Game mentality, etc. If I try to play too physically relaxed, I feel as if I lose a step. But do most people play best when physically relaxed but mentally focused? Thanks in advance.
