Firstly, don't listen to anyone here.
If you feel if you can do it , go ahead. Don't let anyone tell you that you can't make it because they couldn't.
The fact that you are asking this questions means you are not sure and scared to go ahead. So at this point it is your beliefs and your confidence that can help you and more importantly your risk management skills and planning , not suggestions from strangers on the internet.
you need to be responsible and own up to your failures. Don't blame anyone for the the decision to take.
I cannot tell you if you should go ahead or not. But i will tell you this -
It is better to fail at something that you love than succeeding at something you hate. That way when you get older you will not have regrets that you did not take the chance when you had one.
We like to be secure and comfortable all the time because this what is we see all around us and this is what is taught to us by our parents/relative/friends.Few dare to beyond the edge.
Look to people who have go beyond and have taken risk. There are plenty of people on the world. you will not find them here on the internet..
Lastly , whatever decision you take don't base it on the suggestions given here including mine.
