best practice for structure of code

If I need to execute a section of code more than once (not in a loop),  
then I of course create a named method so that I don't have multiple  
copies of the code.  On the other hand, I sometimes create methods  
that exist solely for readability and are only called once, see below  
for example.  Is there any drawback to this style of code?  Are there  
differences in opinion, or is there a widely accepted best practice?

public void init() {
	parseConfigFile()
	loadImages()
	loadData()
	buildGui()
}

This often leads to class fields that could otherwise be local  
variables, which I see as a slight drawback.

I've also experimented with unnecessary braces to improve readability,  
but I suspect this is very unconventional.  For example,

public void init() {
	
	{ // parse config file
		foo
		bar
		etc
	}
	
	{ // load images
		foo
		bar
		etc
	}

	...

Of course any variables defined within the braces are not visible  
outside the braces and working around that can reduce the readability  
somewhat.
