People who can look at problems from a different angle often end up solving them in completely unexpected, often elegant ways. At the same time, they expose how narrowly the majority had viewed the problem, or whether it even was a problem.
Stop looking for what’s wrong about you and everything you want to pursue, and see what’s right about you instead! Focus more on what could go right instead of wrong. When you catch yourself criticising, stop and be realistic about what can actually happen when you concentrate on getting stuff done instead of thinking about them.
