True - but unless your extremely lucky or well connected the probability of success is super low. Throwing together and app to find a sandwich shop is one thing - building a viable business plan and launching a business is entirely different and requires a lot of time to think, understand, research and evaluate to improve your chances for success. Use this time to do the research, talk to your prospective customers, observe and learn from potential competitors, it'll help you understand your market ( or if there even is one ) and find your niche. Once you have all this - at least you'll be better informed to make a decision to pull the trigger or not - at a minimum you'll be able to make a case for yourself to friends, family and potential investors. good luck
