When we are able to approach the Dharma with joy and delight we are able to go much further in our practice. When we have joy in our practice we are less likely to be distracted or become sidetracked. All of that enables us to have even greater joy. But when we cling too tightly to effort and form and correctness we in effect strangle out the delightfulness of Buddhism. Practice the Dharma as if it were and ice cream cone. Enjoy it or it will melt in your hand.
