Hello Aspirant,
First of all don't let demotivate yourself because this will stop from doing any thing. What you have to do is just identify your inner talent because as you have mentioned in your previous question that your past was dark so I will again recommend you same thing that learn from the dark past and enjoy your bright future. Any successful person does not think that whether he/she can be at that place where he/she wants to be instead he/she works on his/her dream then only the moment he/she was only able to dream would be achieved. So just believe in yourself and start preparing without thinking of result because whatever the result would be will teach you something and we all knows that "something is far better than nothing".
