Now if you are going to do a startup and you think your idea is the best and very unique. Well first thing to is to have estimate market value of your idea. Then participate in competition across India and take part in discussions held on forums and Facebook groups like Facebook group of start-up Talky .
The ideas are nothing but a solution to a problem in today's world or the upcoming world in 10 years, all the successful entrepreneurs have one thing in common that is seeing the problems from coming 10 years like ola, Paytm, OYO etc. So try to find solutions of problem that you see coming to you in future years.
The best advice first join a startup if possible and see how they work and cope up with financial issues , HR issues etc. or you can do a small start-up of your own and just go with it , if it fails learn from it and if it succeeds than too learn from it. Then bring your idea to market when you can really implement it with help of investors and team.
Any idea will be successful if you have clear vision, potential and dedicated towards your work.
