It is only natural that we avoid the unknown. We fear instability. We fear loneliness. And above all, we fear failure. Consequentially, we remain within our comfort zones. We chose what is familiar and ultimately controllable.
One of the most important lessons I have learned over the years, is to take risks. Challenge yourself (within reason). Change jobs. Explore a different religion. Try a new hobby. Write a book. Travel. Start a blog! Never let your insecurities or fears limit what you do. Put yourself out there. And most importantly, don’t overthink it: Just Do It.
