All the best laid plans

Which is more difficult?
Planning or Executing?
Formulating or Implementing?
Thinking or Doing?
Learning or Performing?
Talking or Working? and on goes the questionnaire.

In my opinion, for any action there is an equal and opposite reaction.
Ok. That was Newton's law. Let me try again. In my opinion for any action before it gets materialised something should have been ideated prior to it. Coming back to the initial question of which is more important, is the intellectual part more important or the gross and palpable part? Some would opine and rightly so, as there are two sides to a coin which are equally important so does the subtle and gross elements that are equally important. But the secret lies in the quality and the pace at which one makes the transition from the conception of an idea to its implementation.

Sometimes because the idea lacks the desired punch it falls apart. And sometimes getting absorbed too much in the nitty gritty of the practical aspects also causes the execution part to go haywire. Added to this there is one Murphy's law "If anything can go wrong it will go wrong". So what is one supposed to do amidst this seemingly inextricable maze called life?

We all had faced this dilemma in the past,are facing at present and I have no reason not to believe that it will happen in the future.
The topic in discussion is to have a party among friends. The usual barrage of questions like why, when, where, how and who, follows and we more often that not end up in the same square from where we had actually set forth. Democracy is good until every Tom, Dick and Harry comes up with a opinion of his own. Though one's friends doesn't consist of any of Toms, Dicks and Harrys each one will have his or her own opinion which makes it a challenging task to reconcile all these different opinions and to find a common ground.
However your woes won't end at the arrival of the decision. Only after it actually happens can one truly answer the question, which one is more difficult?
The planning or its execution? :-)
