"I think I do better when things are a little tougher"

This quote by Richard Marx suggests that he is someone who thrives in challenging circumstances. He thinks that he is able to carry out better when the stakes are higher and the task is more difficult. This could be interpreted as a sign of resilience and decision, as he is able to press himself to do much better even when the chances are against him. It could also be seen as an indication of confidence, as he wants to take on difficult tasks and thinks that he can succeed. This quote might be seen as a suggestion to never ever quit, even when the going gets hard. It is a reminder that with hard work and commitment, anything is possible.
