You have to create your self-belief by going to your core to find the probable reasons for the negativity in you, and then demolish them.
If obstacles are large, jump higher.

Athletes who are able to stay completely focused in pursuit of their dreams are the ones that are most likely to become champions.
Success is a decision, not a gift.
Share your aspirations only with those who will support you, not those who will respond with doubt or lack of interest.
