There is a legend of a group of Koi Fish swimming upstream and against the current. Most of the Koi gave up and the flow of the river carried them away. There was one of the Koi that kept on jumping and reached the top of a waterfall. The Gods recognized the Koi for its perseverance and determination. They then turned it in to a Golden Dragon which is a symbol of power and strength.
So after all that, here is a reminder that you can achieve anything. Many people will give up. Many will doubt you. But you just need to keep pushing.
