To overcome weather frustration, be prepared with the necessary clothing to compensate for climatic changes. If it's cold, bring more clothing. In wet weather, wear the best rain suit you can afford. It's a great feeling when everything goes according to plan. The fish are coming in steadily, your catch weight is increasing and mistakes no longer plague your day.
Euphoria is a better term.
There are no psychological problems with euphoria. It's a great feeling that is often rewarded with a trip to the winner's podium. You feel good about yourself and you feel invincible. The real problem with euphoria is holding onto it throughout the season. While it is impossible to keep that high feeling during the drive to the next tournament, you can keep your competitive edge.
