Sometimes, pointers are given to you in life. In other times, you ask somebody for pointers. Occasionally, you seek out pointers from within yourself.
Good pointers can lead you to answers. Bad pointers will take you to the wrong destination, and sometimes they bring you back to square one. Very rarely, the right pointer showing up at the right time can possibly change your life.
Just like in photo shooting, looking out for pointers at a scene and being able to capture them at the right moment will produce much more interesting results.
But first, just like setting life goals, you need to visualize the end result that you want to achieve. No point if you are just pointing aimlessly without knowing what you want to achieve.
