You will be successful if you need success as bad as you want to breadth. 

I have experienced this myself when I was about to lose my job and my survival depended on my skills to network and get an offer from another employer successfully.

I really had a deadline for survival and i accomplished amazing results because i was fighting to breadth. It brought unparallel clarify and purpose to my efforts.

also in the process i realized the importance of friends, supporters and people in general.

So my suggestion is that if you have a goal in life that is really important to you - make it so important as if your life depends on it. Whether you succeed or not may not be fully in your control but the focus and clarity that you will feel will be unmatched to any life experience.
