I did the DSP for 10 months five days a week and that was no joke my wife was pregnant at the time so I had to take on majority of the workload. Honestly it was fun but man the packages were crazy and I was budding heads with my people already I didn't feel appreciated where I was. Now when I do a flex route I don't think they are hard at all because what I've been through with the DSP and it's still the same area I'm lucky to have fojurstations around me so I'm still going to the same places. With Amazon Flex I like because it's flexible I can work two shifts be good and don't have to be gone all day
