The need to be accepted by others will always grow out of lack of love. But love from others will never replace the love you can give to yourself.
- Ask yourself: what do you actually like in yourself ?
If the answer is no,
- Then what can you do to start liking yourself as a person.
When you start to truly love yourself, the need for other's approval greatly diminishes, because you don't need it anymore.
That's why personal development is so much linked to seduction. Because if you like nothing in yourself, and you think you don't deserve attention, then why girls would bother ??
Common areas to develop your own self esteem are working on your body (musculation, weight loss, fighting sport...) and your mind (meditation, hypnosis, reframing self talk etc.)
But more basically, take anything where you can start to make progress, the more you make progress in a discipline you like, the more your self esteem will grow, and the less you will need to get other's approval and get rejection so badly at heart
