Imagine Your Goals Like Pushing a Rock up the Hill
If you are pushing a rock up the hill, will you stop halfway and do something else? If you stop, the rock will roll back down the hill. You will have to start all over. The same applies to your ambition and goals, you have to keep pushing it. As you push further, the harder it gets. As it gets harder, you have to work harder.
If you are working on an ambition or goal, make sure you are only focusing on one aim - until completion. If you are distracted or working on multiple projects, it is unlikely that you will not get it done or it takes far more time than necessary to complete.
In this year, aim to do one thing well and make sure you get it done. Do not stop, as you will have to start over.
