Comfort gives you a false sense of security. The reality is, things are always changing and the only way to evolve is to live beyond your comfort zone. Being courageous is not about the absence of fear but rather doing things in spite of fear.
You can't always control the actions of others, but you can control whom you choose to keep in your life. If someone sucks, cut him or her out now. They will only be negative energy that you don't need in your life. You deserve to be surrounded by people with beautiful hearts and good intentions.
