i. the most practical idea (one that could be easily implemented)

A company where working and studying occurs simultaneously

In this case you can be fully involved in real-life coding while you will have a chance to learn what you have not done before.

ii. the most disruptive idea (one that would make a huge impact, regardless of how feasible or affordable it is)

Integrate 2-3 or more options and experiment what works best for you

Integrating different options could be most disruptive for a person. If you choose just one activity and decide to be committed to it for a long time your choice may not meet your expectations. Thus constant experimentation is the key. You can test what kind of studying method is most suitable and exciting for you.

iii. your favorite idea (one idea that you are excited about for whatever reason... you don’t have to justify why)

Form a group of like-minded people to share experiences

Forming a group of like-minded people is a good idea. You are surrounded by the peers who have more or less similar interests and goals. Therefore, it could work as a study circle where you can update your knowledge and enhance your study experience.
