"If you are feeling worthless and try to suppress those feelings, you will never be able to do what it takes to improve. If, on the other hand, you come to terms with your negative self-views and accept the fact that you are not as good as you would like to be and, especially, that you are unhappy with yourself, you will be able to focus on what you need to do to improve.
Dissatisfaction is the mother of change, and only change can drive improvement.
When you actually accept your weak points, your flaws, and your imperfections, then you can motivate yourself to make changes and improve.
What matters is the desire you have to attempt to achieve your goals.
So don't say you lack confidence. All of us lack confidence. All of us have insecurities, doubts, fears... all of us.
Just pick a goal, a goal you truly want to achieve, and take a clear-eyed look at your weaknesses - not so you'll feel less confident, but so you can determine exactly what you need to work on.
Then get to work. Celebrate small successes. Analyze your weaknesses. Keep going." Jeff Haden
