What if you tried to move an object with 'the force' and it moved so slightly you didn't notice? The only failure is in your observation.
What I'm getting at is you have an impact on the world whether you notice or not. Keep doing what you're doing, bettering yourself daily, and you'll eventually make it. Meet your goals. If you don't have goals, you need to make some. Set goals for the day, week, month, year, and meet them.
Keep pushing, you can do it!
