Yes there were a few. But I try to always keep the cost of failure small.
This is how I try to be frugal.
* I see a potential problem, see if I can solve it. See if it's already being solved, if not I pitch the idea to few people. If atleast 50% got excited. I pick this idea to build
* I set a goal on day 1 on what the microstartup should
achieve once its launched. * I try to take no more than 4 weeks to build it.
* I do a public launch in IH, PH, Twitter, LinkedIn, Facebook and Reddit. In few weeks if I reach the goal that I set at the beginning, then I continue working on it to improve. If not then I will drop it and move on the next.
You have objective in making this choice, most people cling on to the sentiment.
