"I understand how it works internally but I have trouble remembering the unnecesary complex command to do simple tasks" I would like to know more which commands these are. Is there something other than push, pull, commit, add, branch, checkout for 'simple' tasks? Or are we talking about syntaxes for setting up like init or doing origin-master stuff?
