Except the founders teaching of Aikido set the goals, mindset, and motivation. It draws a certain type of person for example when the founder says things like this it doesn't really lend itself to competition or fighting in MMA.Those vary from person to person regardless of MA of choice. Not everyone practicing Aikido has the same goals, mindset, or motivation for example.
"Aikido is not an art to fight with enemies and defeat them. It is a way to lead all human beings to live in harmony with each other as though everyone were one family. The secret of aikido is to make yourself become one with the universe and to go along with its natural movements. One who has attained this secret holds the universe in him/herself and can say, "I am the universe.""
