Diving head-first with a difficult problem is a good indicator of progress

a difficult problem is to Start with wishful thinking
when starting to learn, diving into problems are often seen as a bad thing
it is essentially like trying to learn to swim on an ocean
- it could be effective if we have a lifeguard
this sink-or-swim mentality can be great if we're to make a difficult problem as our model for progress
for example, if you're trying to learn 3D modelling by recreating a massive landscape, you can start with it as an initial exercise
at first try, it will fail but you can retry maybe next month to see how well you improve
a difficult problem can give us a clear indication of our progress
contrast this to learning by starting with the simplest possible example
in some capacity, we already have been doing this since we have an idea of what we want to do
- a lot of our inspirations tend to be people with advanced levels
beware, Diving head-first into a difficult problem makes a bad start
