Never accept anything less than you deserve. Remember, you teach people how to treat you. Self-worth is one of the biggest things that society struggles with, and if you doubt that then just look at any advertisement. People over-value themselves, under-value themselves, or don't know how to value themselves at all. Your peers seek out attention on every social media site known to man just to gauge their presence in a fake and fickle internet world. Not to mention, these same people try to emulate the lives they see from celebrities on their televisions. It's not such a big deal to try to impress the world, but in the process of self-evaluation it is important to figure out exactly who you are and what you want out of life.
The second half of this quote is where self-discovery really comes into play, because once you know what you want and deserve you'll know what you are seeking in your relationships. If you don't think highly enough of yourself, you can find yourself settling for anything which means you will accept any version of a friendship or relationship. On the flip side, if you think too highly of yourself you will never make meaningful relationships because you will always feel like you deserve better than what is being placed in front of you. Women and men find themselves in abusive relationships because they genuinely feel like that is what they deserve. This is a damaging cycle and can be one that is hard to pull yourself out of, but only if you choose to see yourself honestly. Don't find yourself caught up in a lose-lose relationship, quotes like this remind us that there are brighter relationships just around the corner with people that truly care and want the best for us.
