Whatever you want to achieve: discipline is going to help you get to it. If people are saying things like “why are you pushing yourself so hard” or “shouldn’t you take it easier”, don’t let that influence your decision. Find people around you that push you forward instead of holding you back. Encourage others to follow their dreams and to move forward.
Being disciplined is not always fun, but when you look back, you’ll be glad you chose the hard route instead of an easy way out.
