Hi George,
Two more points - admittedly a bit obscure!
There's a useful if dying distinction between "I will go" (fact) and "I shall go" (intention). You can still see it at work in the distinction between "Will we go?" (= something like "Do you think it will happen one day?") and "Shall we go?" (= something like "Come on, let's go then - yes?").
As a literary device, we can use the simple present to a similar effect. Famously, James Joyce ends A Portrait of the Artist as a Young Man with "I go to encounter for the millionth time the reality of experience and to forge in the smithy of my soul the uncreated conscience of my race." This doesn't mean "I go regularly ..." or "See? I am in motion out the door right now as I speak." It means "I hereby announce my firm intention that I will shortly be doing this."
All the best,
Richard
