We never lose the potential to learn new things as we grow older. We can master new skills and be creative all our lives. Its true that genes impact our lives but our lives also impact our genes in that our brains change shape according to the experiences we have.
Most of us don't understand that our true inner potential is extraordinary (at any age). The main reason people stagnate is that they limit themselves through habits or mind-sets or simply by setting their sights to low.
By rearranging our thinking, letting go of negative thoughts and behaviors we allow space for new positive experiences and ideas.
