You must be willing to pursue a Ph.D. programme. Take a diary and a pen. Find out a silent zone area. Sit and Think.
Think Why, When, Where, What, Which, How?
What are you currently doing?
Why do you want to do it?
What would you like to do after your Ph.D.? And Why?
How would you sustain (financially) yourself during this time?
Which specialization(s)? Why?
Which institute/ university you would like to apply to? Why?
What are you doing currently? Are you ready to change the status quo?
Until you get the clarity.
