If you cannot give the required time for a work, then don't give it even a little time.Some people make a new purpose for themselves every day, and new desires come into their minds on the next day, and there is no stagnation or stability for them. If you have decided that you want to crack the exam of IAS, then you have to give the required time and hard work for its entire preparation, only then you will be successful. If you give up in 1 or 2 months, then you completely wasted your 2 months.
Being very careful in choosing the career or any work in life, consider all the parameters first, then only take a decision and give sufficient time and efforts for that task. If you cannot do this, then it is useless to give even 5 minutes to that work, because likewise, by giving 5 minutes repeatedly, you waste precious time of your life.
