To isolate the mind from others.
In my opinion, I have to intentionally isolate my mind from others for success.
Because I hate loneliness and to get together with friends is the way to be happy for me, if I am with my friend, I would not strive for success.
Thus, I dare to choose the way where it seems to be difficult for me to be happy.
If I am alone, surpass yesterday's myself is only means for me to be satisfied.
So, I would make a opportunity to be alone both mentally and physically rather than with friends.
