First and foremost, without goals it is really tough to know what your personal priorities are. Without a plan, you won't be able to measure whether or not you're accomplishing anything and if you're not getting the results that you want then it's hard to decide whether or not you should change your approach. Additionally, since there is no endpoint or destination for your endeavours, it's also pretty difficult to see any progress at all. This can lead to feelings of stagnation and resignation since you feel like there isn't anything that you can do about the situation.
