At any point of time, whenever you get a second thought of not following what your heart says or doubting yourself in decisions your heart makes, remember to dismantle any such thoughts.
Go climb that mountain.
Go jump off that aircraft. Skydive into the dreamy realm..
Go on to travel the world..
Go do the work that your heart likes
And go tell that special person that your heart loves them..
Because hey! You only got one life..
