Pikudei Hashem yesharim – MESAMCHEI lev.
See also the Mesilas Yesharim who warns a lot about people getting confused between pleasure and happiness – and ice cream gives pleasure, limmud haTorah gives happiness. It’s getting these two confused that leads a person to depression, which in turn leads to greater pursuit of Olam Hazeh, which leads to depression….
And a private jet or $5000 camera is a large ice cream. Don’t get confused.
And finally, ALWAYS consult Da’as Torah with such critical, delicate matters, where the smallest confusion over a seemingly minor subtlety can wreck a life, R”L.
Hatzlachah!
