how do I restrict myself to a smaller phonem/tic inventory

I find it hard to understand that languages can have 5 vowels. someone teach me the ways of making a less complicated inventory

consonants:

b p d t g k 

m l n ng r w y f v s z š c č h

vowels:

a e i o u ã ẽ õ

is already very small for me so yeah tech me your ways.
