One thing I've learnt through my travels is the simple notion of FLOW. What does it mean to flow with life?
It does not mean that you take no responsibility and let "life" carry you by. In fact, it means the absolutely opposite. You are FULLY aware of your actions, your goals and directions, but you are not rigid to having everything to go solely according to YOUR plans. Instead, you are open to changes and you embrace experiences; whether good or bad, and you consciously go with the FLOW, make adjustments when needed, while still keeping your focus on your goals.
Drop expectations. Nothing in life is for sure, so go with the ever-changing FLOW. Share this positive vibe.
