I think that a big factor in developing a strong character would be confidence. Without the confidence of being who you are, you can never strengthen the character that you wish to be. You have to accept whole with whole heart both the positive and negative part of yourself. That way, you can full understand and embrace the character that you have.Be confident of yourself and stand on your own decision, for me can develop a strong character. You have also to know where you stand on an issue so that you can focus on yourself.by facing your challenges without any fear . Be confidence to stand in front of others . Always think positive .The first and the most powerful discovery, is self discovery. You must first discover who you are your natour and be able to work on that. And again self discipline you must work on your character constantly and be ready to learn from other people in with different views.
