You never understand what your idea can trigger. If you want to launch any idea which you have, either for a service or an item, you've got to be comfortable with taking a risk, you should be comfortable with hearing no, and you need to be okay with the simple fact that not everyone will love your idea. So a lot of people have great ideas of things they want to invent, yet the majority of the time we simply consider it, and shelve it.
Believe me, there are equally as many roadblocks in life because there are running a business. When life requires a route unexpected, you figure out ways to push through and keep going. Sunny, pleasant weather, beautiful beaches, people from all around the Earth, and a the opportunity to create any life you could dream of.
