Life is difficult, isn't it? I accept this as the true state of the world rather than a pessimistic outlook. Life is Good as the t-shirts say and so does God in Gen 1, but life is also difficult. If this premise is dealt with then there are two texts that are meaningful for reflection.
From Rilke's Letters to a Young Poet, p. 53
"People have (with the help of conventions) oriented all their solutions toward the easy and toward the easiest side of the easy; but it is clear that we must hold to what is difficult; everything alive holds to it, everything in Nature grows and defends itself in its own way and is characteristically and spontaneously itself, seeks at all costs to be so and against all opposition. We know little, but that we must hold to what is difficult is a certainty that will not forsake us; it is good to be solitary, for solitude is difficult; that something is difficult must be a reason the more for us to do it."
Choose life so that you and your descendants may live, loving the Lord your God, obeying him, and holding fast to him; for that means life to you and length of days, so that you may live in the land that the Lord swore to give to your ancestores, to Abraham, to Isaac, and to Jacob.
