KNOW YOUR AREA OF EXPERTISE AND FOCUS ON YOUR CORE COMPETENCY!
A person who is expert in a particular instrument will easily identify its sound from many other instruments or sounds in any song or a music 
track 
. His ears are trained and tuned to listen to that sound. His concentration and focus are clear.
Similarly, if our focus in life is clear then we will find our path amidst lot of chaos and distractions.
We should focus on our goals, core competency and excel in it. No matter what other people think, do and advice, our actions should be goal oriented using our core competencies.
May God bless us with the wisdom to have a clear vision, focus and concentration in life!
Tathastu! Swasti Siddham! Amen! So Be It!
