You should be prepared for:

• times when you need to scratch your head
• failures at some point of your study
• harsh but usually constructive comments from your peers and supervisor(s)
• sleepless nights when you do not see a hope in finishing your study

But, you should also be aware of the truth that all that you go through during your study will eventually better yourself in a number of different ways. You will

• get stronger, knowing that all failures and suffers are temporary;
• be able to deal with problems in the field of your study and the beyond; and
• be able to present your work in different ways and to people from different backgrounds.
