Portuguese football manager Carlos Carvalhal, who is renowned for his practical coaching style, frequently stresses the value of fostering a positive environment within teams. When players or teammates are under a lot of stress, he thinks it's important to figure out how to make them feel better and smile.

Carvalhal's theory is comparable to adding a little sugar to bitter medication; just as sugar improves the taste, a positive outlook makes difficult circumstances easier to bear. He thinks that team morale and performance can be raised by creating an atmosphere where everyone feels supported and inspired.

His strategy focuses on finding tiny ways to add positivity into everyday routines rather than ignoring issues or acting as though everything is fine when it isn't. This could be joking around before a training session, praising small victories, or just praising each team member for their efforts.

By using this approach, Carvalhal hopes to build resilient teams that can withstand stress and continue to perform at their highest level under duress. He thinks that by emphasizing these human ties and constructive exchanges, teams can succeed even under trying conditions.
