It can be challenging to continue pursuing a goal when that goal feels far off from where you are at this moment.
Setting large goals is innately a great thing, we wouldn't be where we are today as a society unless people dreamed big. I think it's important to have large goals - I do of course as well, especially in motorsport.
A large goal/task/project though can seem unsurmountable if all that's focused on is the end product. In this time it's important to focus on what's the next small improvement that can be made to move towards that goal.
