Change isn’t always about embracing something unknown. It is also about giving up something old for something new.
Don’t fear change. Whether it is an unhealthy lifestyle, an unhealthy relationship, a job you are unhappy with… ONLY YOU CAN CHANGE IT. If you are not where you want to be in life, change what you are doing. If you are stuck in the past, let go and move on! What you allow, will continue.
