If you want to become an important person, you must turn into an important person step-by-step. If you want to become a successful businessman, you must do so step-by-step. If you want to become a great football player, you must practice day-by-day, and keep on practicing when you don't feel like.
Nothing is done, except little by little. That is a truth we need to understand and accept. It isn't necessarily something we like. When I look at a recipe for making food, I often start looking through the number of steps in the recipe. If it is complicated, if there are lots of steps, I will often look for a recipe for the same food, only with easier and fewer steps.
That might work out, but it isn't always a good solution. So, even though we live in a culture in which we always want the easier solutions, we need to get used to the mentality that we do not get anything for free, and if we want success, we must achieve it little by little!
This principle is also used by those who walk 10-20-30km and even more. It sounds a lot, but in reality, it is mostly about just taking step by step, and not giving up, and in the end, you will reach your goal!
