Start small and build it out.

1) I think you have a little bit of imposter syndrome happening - so check on yourself there

2) start small. For you I would suggest maybe a notebook (like Jypter) and just do one on say matrix cross products (linear algebra). Each time you hit a new concept make a fresh note book and write it down in code. Push yourself here so for example don’t just use a cross product function actually write one.

You will find the note books show your progress and give you some dopamine hit for each task.

3) if you really taking it seriously you will need to do the same with pen and paper small tasks at a time
