There are a few things I've learned from being an engineering student:

1. It made me better at math.

Not the “solve free body diagrams and its accompanying equilibrium equation” math but the “I need a 130% on my final to pull up my grade to a C” math.

2. It made me learn the importance of having connections.

I am part of an underground past exams and textbook PDF dealing community, which has saved my GPA numerous times.

3. Social life.

Non-existent.

4. There's no time to be healthy.

Red bull, espresso and chicken over rice everyday.

5. I learned how to deal with bad grades.

After getting that first C in my class, nothing depresses me anymore because I
already died.

6. Sleep is for the weak.

Just kidding, I need a full night of sleep to function but I have learned to be content with 4 hours.

7. Everything is a physics problem.

After a few seconds I knew that compressive force in the pole and friction from the police officer walking on the wall was what kept him aloft.
