Vexing...

Life is all about decisions making.
That's the hardest thing in life.

Here's the situation.
I joined this competition, I'm the leader of course.
My teammates suggested replacing me with someone else.
So I'm thinking of quitting the competition...
Since they don't listen to me, it'd be useless to stay there being the leader.
Teacher did told me not to give them face, just order them.
But will they listen?
Surely not.

I told teacher about this just now.
After discussing with our trainer, they suggested 2 solutions for me.
1. Quit.
2. Replace them with anyone, get ECA marks, purposely lose the competition.

Let's list out the pros and cons of both solutions.
1. Quit.
Pros
- More time studying.
- Another set of materials for other teams.
- My juniors are given a chance to join the competition and gain experience.
Cons
- I lose ECA marks.
- Wasted the time that I went for the trainings.

2. Replacing.
Pros
- Help 2 friends that can work together with me get ECA marks.
- I get ECA marks.
- We gain experience.
Cons
- A bit lesser time studying.
- Less juniors get the chance to join the competition.
- No guaranteed win.

Both ways can be noble and selfish.
So, which one should I choose?
