Development is an uphill battle. That is the nature of the beast. Development has a way of keeping us humble. If we lose that humility, then we have stopped learning.
The days when we fail are nothing more than opportunities while the days that we succeed should not be focused on too much. If we do, we lose it.
Development brings what it brings and that is usually unexpected. The days are long and hard. Working the minutes is tedious even if it is enjoy it. But the skill developed will proceed overtime to the point where one can look back after year and realize just how far they’ve come.
