After launching 4 products(launched the latest, a couple of months back) in 5 years (1.5y full time Masters). Here is what I realized
1. what is the motivation - a pain killer or a vitamin
2. Decide - Is this to add income to your regular job
3. Decide - If not 2, think of cost to run it
4. Decide - How do you want to manage this, when you wake up next day with another cash cow SAAS idea
5. clarity - time you want to spend on this EVERY DAY, to not regret later
6. Decide - What is that only feature you want to release in the MVP
7. Set - timelines, STOP pressing yourself into the stress; easy goals and relaxed timelines
9. Launch - no better place than HN to release MVP
On top of all these, STOP thinking going fulltime into it until the PROFITS at least match your regular job salary
