If you aren't good at loving yourself, you will have a difficult time loving anyone, since you'll resent the time and energy you give another person that you aren't even giving to yourself.
We need to find the courage to say NO to the things and people that are not serving us if we want to rediscover ourselves and live our lives with authenticity.
At the end of our time on earth, if we have lived fully, we will not be able to say, 'I was always happy.' Hopefully, we will be able to say, 'I have experienced a lifetime of real moments, and many of them were happy moments.'
No matter what age you are, or what your circumstances might be, you are special and you still have something unique to offer. Your life, because of who you are, has meaning.
