"All you need is motivation."
-- Mr. Fernandez (Former UC-BCF instructor)
To truly aspire a challenging life is to do challenging activities physically or mentally. Performing on average will make you satisfied and frustrated because you know you can do better but wouldn't. Being sour with it will attracts sour people like you and you will be bonded for life regretting the opportunity that was.
When we set a goal and actually pursue it, we make our life happier and shinier because it is time well spent. With these knowledge, we will be motivated to perform.
