Can someone please translate for me !!

Here are my suggested translations:

"No heart has ever suffered when it goes in search of its dreams."

Nullum cor sua somnia quaerens umquam doluit.
Nullum --> No
cor --> heart
sua --> its
somnia --> dreams
quaerens --> seeking, in search of
umquam --> ever
doluit --> has suffered

"Let your soul stand cool and composed before a million universes."

Anima tua coram decies centenis milibus universis lenta atque tranquilla stet.

Anima --> soul
tua --> your
coram --> before
decies --> ten times
centenis --> a hundred
milibus --> thousand
universis --> universes
lenta --> cool
atque --> and
tranquilla --> composed
stet --> let stand

Please read this.

Hebrew tattoos generally don't work out very well. If you don't care what I say and still want one after all these years, keep reading.

"No heart has ever suffered when it goes in search of its dreams."
אף לב לא סבל מעולם כשהולך לחפש את חלומותיו

"Let your soul stand cool and composed before a million universes."
תן לנשמה שלך לעמוד קריר ומורכב מול מיליון יקומים

Note this is in modern Hebrew, not Biblical Hebrew.
