In touching the void page 53, you see joe expressing what he feels about ambition and that it is not always good.
When he said “I felt the usual ain’t I climax” that quote shows that he is ain’t as satisfied as he thought he was going to be.
When he says “what now, it was a vicious circle. If you succeed with one dream, you come back to square one and its not long before your conjuring up another, slightly harder, a bit more ambitious- a bit more dangerous.” He demonstrates how he keeps climbing them then when he does succeed in it he’s ego makes him climb a bigger one and he’s scared that he might do one to big.
The example of the quote for me is when I skateboarded down a ramp and there was a bigger one so I did that then after I kept feeling it was nothing until I did the bigger one.
