job or business

Question

Hi, am working as a team lead (same company from last 4 years) in mutinational company having 5yr exp in .net tech., Salary is average and no too much work pressure but I din't see bright future in this company and my major problem is that am not able to decide should I left the company and try to join some big mnc where I get better salary or I keep working here as here I don't have too much work load and I can easily work on my personal projects. But if join any other MNC then for sure am not able to work on my personal projects. As I want to run my own business (software development) but have fear that if am not able to run my own business and keep continuing work here in same organization then my future will be in dark. Can you please provide me your opinion on this please?
