No worries I failed 4 times before I finally found my successful business. All I go to say is don't give up, eventually you'll find that one successful idea that will bring that dream to life. My recommendation is don't go into a niche that has tooooooo much competition (especially the cosmetic business). I would suggest you try to narrow it down to a very specific niche on your next venture. As they said on Shark Tank Once, would you rather have a crumb of a pie or would you like to have a small pie but the hole pie ;)
