Hello David,

Brett imho has given a very relevant reply.

In addition: Whatever you start will at some point lead to some
difficulties and then you need a motivation to continue and overcome
these. At that point a motivation coming from inside you (fun, you
want to have the result, whatever) is much better than external
motivation (money, somebody else's expectations).

Learning happens when you are interested and less so when you try to
accomplish some externally set goal.

So IMHO start trying some of the tutorials as long as you find them
interesting. This will give you some training with the tools. Then
find something you're really interested in and if you estimate it too
big for your skills, start on as many details of the whole problem as
you feel you have ideas for. Things will evolve from there.

One thing I always find interesting is simulations, which often are
the core of games. Make a model of how you think something works,
implement the model, play with it, improve it. The central heating of
my house or traffic jams are two things I don't do since years :-))

And don't forget to ask for help here!

Cheers,

Herbert
