Damn I thought passphrase is just a synonym for password, but a password sentence seems like a better solution, idk why I haven't thought of that.

If you base the passphrase on something related to your Interests, It's not difficult to remember but hard to crack.

For Instance, "I love going for long walks along the beach". Even stronger when substituting letters with numbers: "I l0ve g0ing f0r l0ng walks al0ng the beach". It's only a single letter type change to a number, hence easy to remember what you've changed.
