♡ try being more confident and more friendly to people so that people like you more - being confident helps you make friends, which makes you more popular
♡ if you dont have the ability to do this irl, try doing this on a social media site, such as tumblr, youtube, tiktok, etc. just kindly interact with other people and participate in communities (its easier if youre in smaller communities) and youll end up well-known and well-liked
♡ if you dont have the ability to do either of those things, use a fake social media app such as twinote or something similar like simplyplural or a private discord server. for twinote, its basically like twitter but just for yourself- you can make a bunch of fake accounts and have them interact with you and give your tweets a bunch of likes. for a private discord server, make a few alt accounts and add them to the server and have them interact with you
♡ ask friends/family/partners to treat you like youre really popular
♡ roleplay/daydream/write/etc about yourself being really popular
