what's your best tip to actually be a success on social media? not quick hacks or fixes - what's your best piece of advice for long-term sustainable growth?

I want to be successful on social media, im not looking for sales i just want to be able to grow my account. I see so many videos saying random things (im not sure if any are true) like 'dont leave the app after posting' or 'engage from the bottom up on tiktok' 'use this sound etc'

If anyones grown a successful account on tiktok, what did you actually do to grow it?
