Something every midlaner needs to experience, especially you so-called "mid mains"
Just kill a few waves then walk away... that's it. Just go into river, look at the scenery. Look at the map. Look at how much time you have until the next wave of minions connects... in fact look at how long it takes for your minions to kill enemy minions without your help. You can do so much in that window of time.
This is an important experience for those of you who struggle with literally anything. Its really saddening to see someone claiming to not be having fun because of the enemy laner or brag about how good they are doing or did in game saying things like "but where's muh S rank!" or "omg how am I supposed to carry dis!" while they just sit on their ass in lane all day killing the same person over and over.
Its like watching people deny themselves an entire line of strategies when they refuse to do this, its called "roaming" but this on its own needs more of an umbrella term, one rank up if you will. Just going mia for a while in general.
name any champ that people hate going up against and usually it will be a champ who can never stop pushing or sucks at pushing or both. This applies to more than just midlane but this I think is especially important in midlane.
