Most people are not aware that self-love comes from acceptance. They may think it comes from external things- beauty, money, objects, other people, achievements- but that is not the case. It comes from accepting yourself, your unique qualities, your flaws, your strengths.
Understanding your true nature, what makes you happy, sad, what triggers your emotions, why you do the things you do, what you want in life. Knowing, and learning about yourself cultivates self-love.
You can’t find it outside yourself. Once you are able to accept, and appreciate who you really are. Self-love will emerge, and set you free. This doesn’t happen over night. It takes time, but can be done, and should be for your well-being.
