Let me give you an analogy.
Suppose I have to go to a hill top to view whole city. I know the way and decide to go to the top. Obviously there will be slope, hurdles, valleys, rivers,jungle,animals,danger,pain and joy.
What do you want to do ? Learn from those hurdles or enjoy the thrill and excitement of the journey.
People don’t realise that at times journey is more exciting than goal. Goal ends the thrill with one last blast!
Enjoy your journey and in the process learn from everything. This is life, rest is struggle.
