“I already knew that I shouldn't develop this app for 12 months and then release it and then see that nobody really cares about it I just was disciplined enough to buckle down and then develop it in the first two months of my free year and then launch it”

Ship the first version in two months, not twelve

Sebastian built and shipped both Lift Bear and HabitKit in roughly two months each. His rule: don't develop in isolation for a year and then launch to nobody. Two months gives you a real signal — people show up or they don't — before you've sunk twelve months into an untested concept. Setting a hard two-month ship deadline also prevents scope creep and perfectionism from delaying the learning.
