An obstacle.

Tightening my shoelaces.
Pulling up my pants.
In a crouched position like a tiger ready to pounce.

This is the biggest obstacle I'll ever face, as of now.
Final semester of pre-clinical studies.
What's challenging is the load of work. Studying the current semester's topic plus all the other previous four semester. I know myself, and if I don't focus... :(.
All i need to do is read, understand and familiarize myself with EVERYTHING I have studied.

Dr Nilesh Kumar, my mentor, said it best,
"You're a senior now, act accordingly."
