struggle, loneliness, and love
It is clear that we must embrace struggle. Every living thing conforms to it. Everything in nature grows and struggles in its own way, establishing its own identity, insisting on it at all cost, against all resistance. We can be sure of very little, but the need to court struggle is a surety that will not leave us. It is good to be lonely, for being alone is not easy. The fact that something is difficult must be one more reason to do it.
To love is also good, for love is difficult. For one human being to love another is perhaps the most difficult task of all, the epitome, the ultimate test. It is that striving for which all other striving is merely preparation. For that reason young people - who are beginners in everything - cannot yet love; they do not know how to love. They must learn it.
