I really enjoyed reading your post because of the good knowledge you have and you have also put it down in writing too.
You talked about having a big dream, yes it's not a bad idea, behaving a big imagination can make us achieve our dreams, so we have to work hard inorder for our dreams to come into actualization.

It is still important for us to have faith in God as we keep working hard in achieving our goals in life, even if things are not working out the way we dream and imagine, we can still find joy and happiness as we proceed with life ahead.

I wish you success in your endeavors as you keep working to achieve your imaginations and dreams.
