Reincarnated as Saitama in OPM

Good premise but overall very poor planning and execution. The Author fell into to a very common trap of fanfiction writers which is it is a reincarnation fic of someone being reincarnated into saitama but instead of it being that it becomes a story about a normal (non reincarnated) saitama put in a different scenario ie. Constantly bored, looking for better fights,bald,lives in same city,lives in same apartment,wears the same hero outfit,avoids all attention to him (tbf he avoids attention intentionally instead of accidently bt for no reason then he is a copy of saitama). Most importantly the author often either doesn't think through his own decisions or forgets previous info he has given and their effect later in the story ie. forgets the ages of characters he has previously given, (Fubuki teases her sister about saitama being her boyfriend while she is 1 and a 1/2 years old and tatsumaki is 6 and a 1/2 years old and says fubuki goes to highschool with the mc while 12) doesn't give the mc wishes to remove his baldness only to realise later in the story he absolutely should have, Many different ways he could have resolved problems or story points much more effectively with just a bit of thought or planning (simply could have had a 1 year time skip instead of needing him to be saved by god to unlock his power and get him recruited by the HA as an S class hero also instead of having a normal f year old charge into a monster infested lab to save tatsumaki could have allowed him to train to unlock his power then save her). Honestly my best advice for the author is to get a notebook and write down every piece of advice as well as what he wants to do with this story (ie. main plot points ,romance targets etc) then deleting this one and rewriting it entirely because just leaving the mistakes as they are is a bad idea and just screams lazy.
