One of the most important thing I learnt in my 5 years of development experience is to think learning as a marathon and not a sprint. In my personal projects, I would keep experimenting with different languages, frameworks , libraries, patterns etc. and they would all end as an unfinised github project waiting to be deleted. Whereas in projects done at workplace or as freelancer, the technology stack is fixed and you limit yourself experimenting with too many libraries. At the end of the project there is learning and a finised product to be proud of. Not impliying here that personal projects should not be done, but too much experimenting increases the chances that the project wont go to production. Therefore along with speed, have a direction to reach the goal.

Tip: Unsubscribe from forms on technologies you do not use to avoid distraction.
