BREAK IT DOWN!
Yes! thats the solution!
What?!! You dont believe me! Here's a small demonstration!

When i first saw this Rangoli, i was amazed! It looked too beautiful! At the same time i realised making something artistic like this was way out of my reach! But then i thought back to the words i have written above and said to myself why not break this thing up!
STEP: 1 The basic design!

STEP:2 Adding the Diyas!

STEP:3 some extra design!

STEP:4 Finishing touches!

And there you are!!
When you convert your problem into small steps, they dont look as intimidating and difficult as it once looked! Its a simple trick but one which we very rarely use in life!
And Hence my final word of advice: when faced with a problem, rather than breaking your head over it, try to break it down!
(A Special Thanks to Amruta for the wonderful Rangoli design!)
