In life, almost all difficulties may be considered 'speed bumps' or some other similar word from reaching their own goals.
There are, in my opinion, three main types of obstacles, which are;
-Physical
-Mental/Emotional
-Outside (AKA Obstacles out of your control)
There are countless possible obstacles for each category, but to name a few for each;
-Physical difficulties may include an injury that would prevent an activity-based to be achieved or a disease that affects your inability to move towards a goal.
-Mental/Emotional goals can include disorders, diseases, or certain negative events occurring that can hinder your ability to function normally.
-Outside obstacles can be anything from weather cancelling an event you wanted to complete to a person having to opt out of something you needed them to partake in.
In conclusion, there are countless stops that resist against human goals.
