Maybe not the type of stuff that normally gets discussed in this sub, but the Mushoku Tensei light novels had a profound impact on me when I read them. Obviously the main character is an extreme example, but any young male who finds themselves isolated and unhappy with the state of their lives can find some relation to Rudy and the feelings he has internally. Seeing him go from essentially a self serving and bitter loner to someone who genuinely cares for those around him and works to better himself not only for his own sake, but for the sake of the people he loves really resonated with me and pushed me to let go of the past and work towards a brighter future and to appreciate the people that matter in my life.
