It is not about avoiding the challenges but about overcoming them and coming out stronger everytime. 

He wanted to become an IAS officer and prepared for exam.  After 2 attempts he gave up and decided to start a business.  He failed in business, so he took up law and his practice did not work.  After trying like this for 3 years, he was fed up trying many options and he wondered where was he failing in life.  He realized he had not been determined to achieve anything.  He was not persistent.  So he sat and thought what he really wanted to do in his life and he realized he wanted to be an IAS officer only.  He started preparing again and this time he cleared.  Sometimes we call it luck, sometimes we call it timing or we may hold anything responsible for what we are doing in life.  But in reality it is our firm decision, determination and perseverance to keep working towards whats we really want to achieve in life.  If we would give up, we would never succeed but if we continue to strive harder every time we would reach our destination.  It is like we keep changing our roads as and when we see a small problem in that road.  We see a small bump in the road and we give up.  We change the road and then we change the next road. 

This way we can reach no where and we would end up spending all energy in changing roads. 

In life we can achieve anything we want.  However, there are few things which we have to follow:

We need to decide what we want. 

We need to focus on achieving it rather than obstacles on the way. 

It is not about time, it is about determination to achieve that. 

Keep trying and you will crack it. 

If you are determined, the whole Universe will support you.  Because you hold Universe inside you.
