M.BA: Here you will have the chance to learn about the management and communication and it is a great field for a budding business personal and as you have a background from economics field, it will open the gates for many opportunities for you to have guidance on business management if you opt for M.BA. As you have a professional level training and grooming and for the backup you can always choose for the job in management if you ever change your mind.
2. Technology field: If you decided to go for the tech field you have the limitless resource for the technology oriented programs and these courses also offer some basic guidance on personality development and business orientation and one more plus point is that you have another handy skill of programming as a backup plan because there is always need for a good programmer in today's era in case you starting loving programming more.
