This, for me, is one of the most powerful sayings that I have heard in my life. Many of us face trials and tribulations in our life that make us want to throw in the the towel, and one of the most difficult moments in our life where we want to give up is when we decide to follow our passion.
You Have No Way Of Knowing How Things Will Turn Out
Once you choose to pursue your passion it is normal for negative thoughts like, my parents were right and I shouldn't have chosen this, or, my friends were right I am not good at this, or, this job is so unstable and won't pay me etc. to creep up on you. These will try to derail you from persisting and going all the way with your passion. What does giving up do to you? Even if at the moment the current situation may not look promising, you have no way of knowing how things will turn out, so don't give up. You know that by pursuing your passion you will be happier, feel free and live the life of your dreams eventually, so by giving up early you are stripping away all these wonderful feelings from yourself. In addition, you are killing your potential early, you don't want to live with regrets knowing that you should have followed your heart instead of choosing what other people chose for you, have confidence in yourself and chase that dream of yours knowing that you are capable of achieving it.
You only need one person to believe in you, and that is yourself!
