It is normal to feel frustrated but saathi ho have patience. As long as you use your time here constructively and not waste it, that is what matters. You can still educate yourself later, it is never too late. Work hard and save up.

I also have not realised my ambition yet and have postponed it. But i have to be patient. :). Plan properly and if you have to go back to achieve your goals and ambitions, do just that. But work on a plan.
