Info PhD programs are seemingly endless, but this path really is more than just a series of projects. I'm "thinking of a series of dreams" (Bob Dylan) while I keep learning over and over that it's best to just suck it up and have trust!
Keep your face toward the sunshine - and the shadows will fall behind you.
"Now Jos Dunny was from FlorI-dee
Where the cotton blooms and blows
Why she left her home in the South to roam
'Round the Pole, God only knows.
She was always cold but the Boiler gold
Seemed to hold her like a spell;
Though she'd often say in her homely way
That she'd sooner live in Hell." (Adaptation by AK)
