In order to do this, I highly suggest you to follow accounts that showcase their work, NOT their looks or latest purchases or which fancy hotel they are currently at. Follow "ideas" so you feel inspired, not "somebody's life" that leaves you feeling jealous or left out or eager wanting to keep up.
If you're into fitness, follow accounts that make you feel like you want to move and exercise because it will make you feel happy and good about yourself, not a fitness account that makes you feel like you need to have that perfect peachy butt. The goal is to be healthy and fit, not necessarily toned with flat abs and a thigh gap. This is the difference. We do not need to fall into the trap that a "great body" is a body that is _____. Embrace your own body. Stay active to be healthy. Do not be obsessed with a certain look or body weight.
If you're into fashion, follow accounts that make you understand that style is personal and fashion should make you feel empowered. Understand that one does NOT need to keep up with the fast pace of fashion influencers always having the latest 'it' bags. It is an illusion, a competition you do not need to participate in. Here's an example why: many fashion influencers often share photos of them with new designer bags regardless these bags were gifted to them or borrowed. Imagine an actual follower wanting to always keep up with their favorite influencer, said follower would actually spend $1,500 for that bag. Ironically, the actual influencer didn't even own / buy that bag, they just took pictures with it as photo props. It's nobody's fault, of course. But while fashion influencers keep sharing new #OOTDs that make you want to buy what they are wearing, they are not spending a dime. In contrary, a follower might end up spending all their salary for the things they see on social media trying to replicate somebody else's feed. So stop. Buy the things YOU actually love. Shop smarter. Browse an actual shop yourself and see which products truly make you fall in love. Buy something because it sparks joy in YOU, not because somebody on Instagram was wearing it.
If you're into traveling, I suggest following a certain #hashtag compared to following a traveling influencer. Sometimes, we get caught up with the person instead of the actual place. Instead of thinking "oh what a beautiful island, I need to save up to visit that place soon", as human beings we often end up thinking "oh she's there and she's taking great photos there, I need to do that too", which basically means you're missing the point of traveling. Traveling should be about the place or the experience, not another bucket list competition because of your #FOMO with other people. By following a certain #hashtag like #waterfall or #lavenderfield, you're putting the emphasis on the place, not the person.
I've been following only artists, designers, brands that I love so much and news / media accounts, and my Instagram is actually my happy place because I like what I see.
