At the time, I was super stressed. I was working three days a week to pay for grad school and having to work pretty much every single day with barely any money to live on was hell. Start-up life, for me, was almost like a holiday. I was working regular hours, and although there were times where I was working hard and long hours it felt structured.
That being said, I absolutely loved grad school. The idea of it is what made me do it. My bachelors in CS left me wanting to know more, so a step-up was required.
I let my university know that I was struggling to make ends meet and that I would be leaving as I couldn't afford the next term. The university where I got my bachelors was as tight with money as possible, so I expected nothing, but they refunded EVERYTHING and wished me luck. I effectively got almost three months of education for free.
For that reason, I will return to grad school, and I will definitely continue it at the same university. Sadly, the price of a Masters degree in the UK has almost tripled, so it won't be any time soon. It if goes down to around £5k I'll definitely do it again.
