Beginner's Mind Vs. Expert Mind

Loved it! I am actually in a space in life where I am going through this "again" phase. I try to take it from the side of wisdom and walk along with peace but after covering a certain distance again the "again" strikes leading to misery. I try to gather all the courage and continue walking with wisdom. So this has been an on-and-off process for the past year now. It is like going back and forth. Still, I believe that life is taking me ahead and would like to listen to the wisdom that says "Don't worry about the back and forth, life is such that it takes you three steps ahead and brings you two steps back. But every time, you are one step ahead". Ultimately, though silently and subtly, wisdom wins!
