Allow yourself to make mistakes (and truly be okay with it!). One of the biggest barriers to self-love is expecting yourself to be perfect! You're human and you're allowed to make mistakes. Where I find this the hardest is in workplace or academic situations. When someone else is telling you that you've made a mistake, it can be the hardest pill to swallow! In reality, however, you are always your own harshest critic. If you make a mistake, correct it, aim to do better next time, and let it go. You know the thing about mistakes? Everyone makes them and it's okay!
Indulge in the things you already love but also try new things! The things you love and the activities you enjoy are huge parts of your identity. I'm a homebody so I love cozying up on the couch, decorating my apartment, and lighting candles. Every time I do one of those things, I feel a little closer to myself and love the happiness that those activities bring to my day! It doesn't matter what it might be - if there's an activity or even an item that you love, take a moment to indulge in things that make you, you! Part two of this, however, is to try new things! As humans, we are creatures of habit so we like to stick to things we know. Experimenting with new things may be a little uncomfortable at first, but it helps you along in the process of self-discovery and self-love!
Seek understanding & acceptance. I began by titling this one as just "acceptance" but self-understanding and acceptance are so closely tied that it's hard to mention one without the other. The negative self talk I used to hear in my head day in and day out always went something like this: "Why am I like this?" or "Why can't I be like that instead?". I struggled with self-acceptance because these questions were always accompanied by frustration. Instead, these questions should have been approached with genuine curiosity. When I started to seek out books (Quiet, by Susan Cain), podcasts (Highly Sensitive Person Podcast), blogs (INFJ blog), and whatever else I could find to try to understand myself - rather than change myself - my whole view changed. You are you. There are a lot of things about you that are probably never going to change. The best way to work towards self-acceptance is to commit to increasing your self-understanding through learning.
