Hi. Hello, good night to everyone.
I spend my money however I like.
Is 'however' proper in this context?
Thank you in advance.
Yes, I believe you can say that. Here's a similar example:
You can do it however you like. Longman Dictionary - however
By the way, I believe you meant to say "good evening" instead of "goodnight", which is used when you want to say 'bye' at night or before going to bed.
