You could be right. It could also be that if your friend was supportive and was excited for you that you would still be motivated to succeed.

I have a feeling that you're striving in spite of the lack of support, not because of it. And also that your own creativity and persistence is able to turn lemons into lemonade. So whatever your friends gave you, you'd take it and make it work.

I'd say all of that is the complete opposite of what people do that are destined to fail.
