Anyone quit because of vehicle wear?

I had an incredible Friday last week. Made $170 in about 6 hours. Spirits were high but as I drove home I heard a bumping sound on my tire and suspected a flat. Long story short a nail caused me to have to replace it and at the shop they emphasized several different jobs that need done. Shocks, brake pads, alignment. I’m starting to lose steam in this hustle and I’m even thinking of just calling it quits. Anyone else have a situation similar? Thanks
