My technique for pi is to identify patterns. The sequence "847564" occurs in pi. I split it into twos. 84 75 64. Notice how the first number goes down and the second goes "4-5-4". I use these little patterns to create large strings.
Kimi wa ne tashika ni ano toki watashi no soba ni ita
Itsudatte itsudatte itsudatte
Sugu yoko de waratteita
Nakushitemo torimodosu kimi wo
I will never leave you
