These are lessons learnt from an entrepreneur’s viewpoint with no political leaning.
1. Quickly accept mistakes & learn from them: Kejriwal was quick to accept his mistake in resigning, thereby, taking the wind out of the BJP & Congress’s line of attack.
2. Learn to walk before you run: The AAP tried to expand pan India after the 2014 elections & failed miserably. Now, the focus is to succeed in Delhi and take it from there. Don’t spread yourself too thin. Focus. 
3. Trust Yourself: Despite the disastrous showing at the general elections + mass internal revolt, Kejriwal focussed on his purpose. Having blinders on, focus, self belief & drowning out the noise is what is important to achieve success. Even when his supporters like Shazia Ilmi & Kiran Bedi left his side, he stuck to his purpose.
4. Look for the path hidden from the world: It seemed impossible to create a credible Political Party with little funding & no ‘movie stars’ in a short time. Challenged by Congress & BJP leaders, Arvind Kejriwal achieved the impossible with strategies whose results only he could foresee.
5. Oportunities exist if you look hard enough: With the decimation of the Congress in the general elections, AAP has been quick to spot & grab the vacant spot of the secular alternative to the BJP in Delhi. Success in Delhi will be the base to launch themselves Pan India as ‘the’ secular alternative to the BJP.
6. Bide your Time: If you work diligently & have consistency in purpose, you will get your chance. It is not who wins the battle but who wins the war that matters. Focus on sustainable differentiators which can scale when the opportunity & right time is right. AAP stuck to giving an honest, secular & equal opportunity government which acts.
7. Technology as a leveler: AAP kept a close watch on the voter sentiments through social media & other means & continuously modified their campaign tactics & strategy. Thereby running a very cost effective campaign against well funded campaigns of the BJP.
As an entrepreneur, don’t let competition deter you, bigger pockets scare you, naysayers dissuade you. While people waste their time discussing, arguing & contemplating, get down and act. You shall yet have the last laugh..
“First they ignore you, then they laugh at you, then they fight you, then you win.” -Mahatma Gandhi

Its one of the biggest turnarounds in the Political History. Now its very important this man delivers for next 10 years before e is ready to take on post of PM he very early started to crave for. My Political Ideology supports both Narendra Modi & Kejriwal. That Ideology is called Nationalist and I guess every Indian should have one.

A comeback means nothing except another shot to DELIVER
What I would love to read is WHAT Arvind Kejriwal did to the nation and Delhi and NOT HOW he climbed back from a well
Sorry – just being my nasty self

Actually, am intending to write a post on that line. When does a startup succeed.: Funding be the hallmark of success vs than creating a profitable, scalable, cashflow postive company with great culture and differentiation, having given profitable returns to investors if any. I believe there is too much focus on raising funds( which serves the purpose of VC’s) in the startup world rather than building companies that last.
And going by Arvind Kejriwal’s actions, I would judge him to be a ‘lambe race ka ghoda’. He has already declared his intentions of not contesting any other state elections this year and consolidating Delhi, just as I had predicted.
