Thanks for all the advice guys! So you think I should start using 'tamani' when in a sentence, and 'tokidoki' when it's a one-word answer?

e.g. Sometimes, I go to school
Tamani, gakkou ni ikimasu.

and

A: Do you go to School? B: Sometimes...
Gakkou ni ikimasu ka. Tokidoki...

Another point: I was having a bit of trouble using wa and ga in sentences. Almost every textbook or online learning page says you should roughly translate 'watashi wa' as 'as for me...', but that never really stuck for me. Would it be ok to think of it like this:

Watashi wa ongaku ga suki desu.
'About me, it is music I like'.

Supootsu wa tenisu ga suki desu.
'About sports, it is tennis I like'.

Watashi wa Yuko desu.
'About me, I am Yuko'

Watashi ga Yuko desu.
'It is me who is Yuko'

(Ignoring the fact that 'watashi wa' is rarely used in day to day language. In fact, this kind illustrates why it isn't? You wouldn't say 'about me' in every of your sentences in English either. Ok, the logic isnt perfect, but it works for me...>.>)
