"Don't be afraid of change. You may lose something good, but you will gain something even better"
Being so comfortable can make us afraid of change. We don't want to lose anything that we have 'worked' for because it steadies our lives.
However, life on Earth is constantly changing and this is needed to improve life here.
Sometimes, life is even better after that change and we (may) have more, or things we had not even thought about, making life richer for us personally.
An example would be a woman having a baby, although terrified of the changes in her body and to her lifestyle, when that baby is born and in her arms --- there is no feeling like it!
So, have faith in yourself and in life in general, because most people only want the best for themselves and others.
LIVE AND LOVE LIFE!
