The freedom to fail is vital if you're going to succeed, most successful men fail time and time again, and it is a measure of their strength that failure merely propels them into some new attempt at success.
The man without a purpose is like a ship without a rudder - waif, a nothing, a no man. Have a purpose in life, and, having it, throw such strength of mind and muscle into your work as God has given you.
The memories of my family outings are still a source of strength to me. I remember we'd all pile into the car---I forget what kind it was---and drive and drive. I'm not sure where we'd go, but I think there were some trees there. The smell of something was strong in the air as we played whatever sport we played. I remember a bigger, older guy we called 'Dad.' We'd eat some stuff, or not, and then I think we went home. I guess some things never leave you.
The “stream” we call science always flows forward; sometimes reactionary beavers block its flow, but the stream is never defeated by this; it accumulates, gathers strength; its waters get over the barrage and continue on their course. The advancement of science is the advancement of God, for science is nothing but human intelligence, and human intelligence is the most valuable treasure God has bequeathed us.
There are pauses amidst study, and even pauses of seeming idleness, in which a process goes on which may be likened to the digestion of food. In those seasons of repose, the powers are gathering their strength for new efforts; as land which lies fallow recovers itself for tillage.
