"The true mark of maturity is when somebody hurts you and you try to understand their situation instead of trying to hurt them back." // (I don't want to label what "the true mark of maturity" is, but this idea of empathy vs revenge is important to me.
There's no point in consistently worrying about everything. What will happen will happen regardless. So breath, look on the bright side. Have some laughs, fall in love, accept what you can't change, and carry on. To actually live is courageous.
