so, our protagonist clearly wishes not for cheat skills since he knows that they don't lead to happiness,
so my dear god, why do you make him not only heir to a noble family which gives him a lot of responsibility but also these way to op magic? in this world even dual elements is considered genius - and he has all six?!? not to mention being able to use them as toddler when ten is normal?
for an easy life let him be reincarnated in a rich, caring family, yes, but as the second or third son, give him one popular element and a high aptitude for it, so he has a good material basis to start his life - he already stands enough out with his unusual high intelligence from having the brain of a (smart) teenager
