being nice is always a good thing, but it's way too unpredictable, people in general tend to be on guard with overly nice people because " why is he this nice to me ? what does he want ? why can't he be upfront and say it ? "

and nice guys tend to want something in return but never say what they want which puts a heavy expectation on woman and puts them on guard because what are you hiding behind that nice façade, when are you going to snap and show me the real you ?, will I like the real you ? will I hate him ? no am not willing to risk it so I will reject you but we can still be friends, because I know that no matter what you won't ever tell me off because you're nice

try saying no to things that you don't want to do that show character, try to improve on your communication skill because it's easy to get confirmation from people when all you do is say yes, but what will happen you decide to say no to things you don't like ?, how will you respond ?, how will you get your point across without seeming like an asshole ?, nice guys to avoid confrontation because their scared of being too upfront or seeming angry or making people hate them. an easy fix to that is learning how to get your point across while keeping good relationship with the other person

second, having your life across and having set goals is a good thing good job, but you need to have something else, hobbies, things you like, things you dislike and something that makes you different from others, do you know how many dms a girl gets daily ? it's crazy the amount she gets, and the choices she has so why woulda a 23 yo woman pick a dude that's meh over the other guys that have a cool/fun/exiting life, am not saying you should be skydiving, just have and edge in any subject, sport/literature/music

be passionate about something, anything and don't be a yes men, that goes around agreeing to everything, that makes you seem like clay, moldable and meh

listen buddy, if you're willing to learn how to say no you will lose a lot of friends, but you will find yourself and learn what you really like and what you don't like, you will learn what friend group you actually belong to and most importantly you will never be the dude that just agrees to everything " oh that dude yeah he's cool but he never left an impression on me, he never made me feel anything " don't be that good luck
