Fear
Control the fear in your life, unless you want your life to be controlled by fear. Every day, do things that scares you.
Even your deepest fear can be conquered. Expose yourself to the things that scares you the most, and experience how weak these chains of fear really are. There is nothing to fear but fear itself. Set yourself free.
In your life, do you move away from your fears, or do you move towards the things you desire? Be careful if fear pushes you in the wrong direction. Progress towards what you want, even if it scares you. This is what bravery is for, and having a lot of it makes a huge difference. Don't put your life on hold because of your fears.
“It is not death that a man should fear, but he should fear never beginning to live.” ― Marcus Aurelius, Meditations
