To put it out in words, multi signature wallets are used in cases of controlled spending basically in cases where more than one person has to sign the transaction for it to get broadcast. Using this for your your personal funds is not necessary and is more stressing. Storing your keys and  seed from a standard wallet is enough for a normal HODLER.

Aside from escrow like cases, big exchanges use multi signature wallets because of the high level of security they demand but for an individual it's not actually necessary.
