The world is becoming a smaller place day after day and it is clearly out there that you don't need to be that loaded to explore a new place every year. I am not saying that travel is for everyone, I just say that you should give it a try and see if it works for you. It may hurt you but trust me, monotony will kill you. 

And if you are scared to travel alone you should know that, you never really travel alone. The world is full of friends waiting to get to know you.
