2 things you cannot do without for long. Anyway, was so tired that we slept at 9.50pm till 7am! Yes, it was really tiring for me. Too many things (not work related by the way) to think about and plan for the future.
But it is worth it.
For though by this time you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. You need milk, not solid food, for everyone who lives on milk is unskilled in the word of righteousness, since he is a child. But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil. (Heb 5:12-14)
It is worth it.
