the way i see it..
basically, why try "level 4" at something, when you can do level 1,2,3 before it?
If they are easy to get done for you, great. Youll just do level 1,2,3 real quickly
and will get to level 4 then.
If you have some difficulty doing level 1, why wouldnt you work on that first step,
that first level, instead of jumping to level 4 right away and get discouraged?
Of course like with anything in life, including this SA program, you can, by choice, by curiosity, or whatever, try something more advanced. You wont die if you do.
But you dont keep trying that thing thats too advanced for you and only frustrate you
and discourage you because its a bit ahead of what you can do.
Small successes in the order of things makes sense, and you know it, and you will
make those smaller successes much more quickly, and theyll build on top of each others.
A pitfall with keeping trying something thats just too much for you(as opposed to starting with step 1,2,3 etc) is that if you go to the places/situations where you experience the most extreme social anxiety every time, then you'll create an association deep in your brain between that place/situation and extreme social anxiety.
So instead of getting better in this particular situation/place, you'll actually experience the extreme social anxiety more and more automatically in this situation.
...to the point just thinking about it will almost cause extreme SA.
so start with small things and work your way up.
hope this helps
