I felt the same way too until last week. If I am ever going to work on something then it should be some kind of a breakthrough product that solves a problem perfectly and all that. But I realised that if I am not going to start small I am never going to start at all. So, I thought of an idea for 2 days and started working on building MVP. My plan is to just get to the next step and not to be stuck here forever cause I am planning to build a product for past 2 years now.
