Wanderlust and Adventure

Do you ever get the overwhelming desire to travel, venture onto new things, be adventurous and be somebody else?

I think in life we tend to surround ourselves by the things we think we can accomplish easily without getting put down or not succeeding, the things we wish we could succeed in e.g. inspirations from other people that we think could never happen to us, and our goals, hopes and dreams.

The main barrier stopping most of us is the way we view our limits, strengths and intelligence. We put ourselves down or we narrow down our options due to what we perceive we can do and what we can push ourselves to do. After-all, anything is possible if you really want it right?
Why do we limit ourselves in this world to what we get told we can do, or what we choose to believe we are capable of? As humans we are made to adapt, grow and change. Therefore why do we need to put a limit on our accomplishments?
