You are confined only by the walls you build yourself.
As humans, we have this unique ability to create limitations of our abilities. Unfortunately, the more self-aware we become, the more we focus on our weaknesses and therefore start limiting our ambitions.
We convince ourselves that there are things beyond our reach and we should not pursue difficult tasks or else we would fail and feel miserable. Break all these mental shackles today as they are all lies we tell ourselves.
Work on your dreams today no matter how delayed you are; you will be successful only if you believe so.
