I loved DBS and DBGT. No matter what anyone says, the one thing which Dragon Ball constantly speaks about is never to lose one's ideals.
Be it Goku's thirst for fight or Vegeta's pride.
No matter what anyone says, if anything can make you go and put your best—even if it is a completely unorthodox thing—treasure it. Treasure that thing and use it to exceed everyone. In expectations a well as achievements.
