To create something, we need a decision and a plan.

Research the topic you are interested in. Decide what result you want. Write a plan and start executing.

Most likely, lots of things will be inefficient and will not work the way you thought and planned, but this is exactly what you need to get experienced and more efficient.

After some time, you may even stop, rethink, and replan based on new info and experience you have.

The more focused you are and the more attention you pay, the quicker and more effective the progress will be.

This is your world. Act like it!
