Front Wing (The Fruit of Grisaia)
Experience is the most useful possible form of knowledge. A precious privilege, reserved for those who manage to stay alive. Sometimes, the most instructive and memorable lessons of all come from the deaths of your comrades. But I wasn't trying to preach to Makina, or make any complicated argument about her values. I just wanted to get across that ignorance isn't something you should cling to proudly. You're only embarrassing yourself when you insist that you hate some food you've never eaten.

Those who do not exert the least amount of effort are unqualified to envy the talented. Those who cannot succeed are unable to because they cannot imagine the painstaking accumulation of hard work by those who do.

You pass. There's no value in a world that's always as you want it. And there's no meaning in happiness you didn't earn. Even if it's painful, even if you feel like you can't bear it at times, it's only through overcoming harsh realities one after another that you will achieve true happiness. Never forget that.
