If you want to express something that you "would like to do," 想 (xiǎng) will be a very helpful auxiliary verb to know. Although similar to 要 (yào), 想 (xiǎng) will give you another more tactful option when you want to articulate a desire.
The verb 想 (xiǎng) can be used to express "would like to." In this case it's an auxiliary verb.
Subj. + 想 + Verb (+ Obj.)

Negate 想 (xiǎng) with 不 (bù)
No surprises here: use 不 (bù) to negate 想 (xiǎng).
Subj. + 不 + 想 + Verb + Obj.
